4.2.1 Internal and external recruitment
The need for recruitment
Recruitment: the process of finding and attracting suitable people to apply for a vacancy in a business.
- Replacing staff who leave: people retire, resign to join another business or are dismissed, and the work they were doing still has to be done.
- Growth: a business opening another site or serving more customers needs more people, so a cafe adding a second branch has to hire a whole new team.
- New skills: a change such as starting to sell online creates a gap current staff cannot fill, so the business recruits someone who can run the website.
- Seasonal demand: some businesses need extra staff for a few weeks only, and take them on for that period rather than all year.
Tesco takes on thousands of temporary staff each Christmas for the seasonal rush, while at the same time recruiting all year round to replace checkout staff who resign, so a business often recruits for several reasons at once.

Internal recruitment
Internal recruitment: filling a vacancy with somebody who already works for the business.
- How it works: the post is advertised inside the business, on the intranet or a staff noticeboard, and filled by promoting an employee or moving one across from another department.
- Cheaper and quicker: there are no adverts to pay for and no agency fees, and because the person is already on site there is no notice period to wait out.
- Less risky: the business already knows how reliable the person is and how they treat customers, so it is less likely to appoint somebody unsuitable.
- Motivating: seeing colleagues promoted shows staff there is a route upwards, which encourages them to work hard and stay, so fewer people leave.
- No new ideas: an insider only knows how this business does things, so nothing is brought in from elsewhere and poor habits are carried into the new role.
- It leaves another vacancy. Promoting somebody empties their old job, so the business still has a post to fill, and colleagues who applied and were turned down can be left resentful.
Greggs promotes many shop managers from its own counter staff, so the new manager already knows the products and the tills, but the counter job then has to be filled.
External recruitment
External recruitment: filling a vacancy with somebody from outside the business.
- How it works: the vacancy is advertised outside the business, through job websites, the local press, a recruitment agency, a jobcentre, a shop window or word of mouth.
- A wider pool of applicants: anyone qualified can apply, so the business has more people to choose from and a better chance of finding the strongest candidate.
- New skills and ideas: somebody who has worked for a competitor brings methods this business has never tried, and can fill a skills gap nobody inside could fill.
- More expensive: adverts and agency fees cost money, managers spend paid hours reading applications and interviewing, and the newcomer needs induction training before they are fully productive.
- Slower: advertising, shortlisting, interviewing and then waiting out the successful candidate's notice period can take months, during which the work is not being done.
- Riskier: the business only knows the person from an application, references and an interview, so it can appoint somebody who interviews well but works poorly, and existing staff may resent an outsider being brought in above them.
Internal and external recruitment is about where the candidate comes from, not about how the job is advertised, so a business that puts an advert on a job website is recruiting externally even if a current employee happens to apply.
Choosing between internal and external
- Internal recruitment fits a vacancy that has to be filled fast and cheaply when somebody inside can already do the job, and it rewards loyal staff.
- External recruitment is the only real option when no employee has the skill, such as Dyson needing another design engineer, and when the business is growing and needs more staff in total rather than a reshuffle of the ones it has.
- Many businesses advertise a post inside and outside at the same time, so an internal candidate can apply but is judged against outsiders.
Once the business has decided where to look, it works through the stages of recruitment and chooses selection methods, which are covered in the article on the stages of recruitment and selection.
- Give three reasons a business needs to recruit.
- Define internal recruitment and external recruitment.
- Give two benefits and two drawbacks of internal recruitment.
- Why is external recruitment riskier than internal recruitment?
- Why might a growing business have to recruit externally even when its internal candidates are strong?
4.2.1b Stages of recruitment and selection
The stages in order
- The process runs in a set order: job analysis, job description, person specification, advertising the vacancy, shortlisting, selection, then the job offer.
- Recruitment is the part that attracts applicants, while selection is the part where the business chooses between the people who have applied.
- Each stage is built out of the one before it: the advert is written from the job description, and the shortlist is judged against the person specification, so an error at the first stage sends every later stage after the wrong person.
Job analysis
Job analysis: studying a role to work out exactly what tasks it involves and what skills are needed to carry them out.
- The manager works out what the job actually involves, often by watching the work being done or asking the person who is leaving, and notes the equipment, hours and training it needs.
- Job analysis also tests whether the post is needed at all, because the tasks may be shared out among existing staff or the role may work better as two part-time jobs.
Before replacing a driver who is leaving, a Warburtons depot lists the routes covered, the 4am loading and the weight of the crates, so the advert asks for the licence and the availability the job genuinely requires.
Job description and person specification
Job description: a document setting out the tasks, duties and responsibilities of a particular job.
Person specification: a document setting out the skills, qualifications and qualities somebody needs to do that job well.
- The job description is written first, because the business has to know what the work involves before it can describe the person capable of doing it.
- A job description gives the job title, the main duties and responsibilities, the hours, the pay, the place of work and who the employee reports to.
- A person specification lists the qualifications, experience, skills and personal qualities needed, usually split into essential requirements and desirable ones.
- For a delivery driver, deliver parcels on local routes belongs in the job description, while a full clean UK driving licence and a polite manner with customers belong in the person specification.
- Having both documents in writing keeps the process fair and consistent, because every applicant is judged against the same stated requirements rather than one manager's impression.
- The commonest confusion in this topic is between the two documents: the job description describes the job, the person specification describes the person.
- Use this test: serve customers at the till is a duty, so it belongs in the job description, while friendly and reliable is a quality, so it belongs in the person specification.
Advertising the vacancy
- The advert is written from the two documents, so it states the duties, the hours, the pay and the requirements that applicants must meet.
- Inside the business a vacancy is posted on the intranet, on a staff noticeboard or in an email to all employees.
- Outside the business it can go on a job website, in the local paper, in a shop window, through a recruitment agency, at a jobcentre or on social media, and the choice depends on where suitable people will look: a shop window suits a Saturday assistant, a specialist website suits an engineer.
Because a Nando's advert states that weekend availability is essential, people who cannot work weekends rule themselves out before applying, which saves the manager reading their applications.
Selection methods
- Shortlisting: every application is compared with the person specification and only the closest matches go forward, which keeps the number of interviews manageable.
- Application form: the business designs the form, so everybody answers the same questions and the answers can be compared side by side.
- CV: the applicant writes their own summary of education, experience and interests, which costs the business nothing to produce but is harder to compare because everyone sets it out differently.
- Interview: questions asked face to face, by telephone or online show how a candidate communicates and whether they would fit the team, although a confident talker can interview well and then work badly.
- Tests: a skills test shows whether somebody can already do the task, such as a trial shift in a kitchen, while an aptitude test measures potential such as numeracy or problem solving.
- References: a statement from a former employer or a teacher checks that what the application claims is true and that the person was reliable and punctual.
- Most businesses use two or three methods together, because no single one shows everything: an interview judges manner while a test proves ability.
Aldi asks candidates for store roles to complete an online test and then attend an interview, so it checks what they can do as well as how they deal with people.
- For explain the difference between a job description and a person specification, give one sentence on the document about the job and one on the document about the person, with an example of what each contains.
- For outline the stages the business would follow to appoint a new manager, keep the stages in order and name each one, rather than writing generally about hiring people.
- If you are asked to recommend a selection method, name it, say what it reveals about the candidate, and match it to the job in the case, such as a trial shift for a kitchen role.
- List the stages of recruitment and selection in order.
- What is job analysis, and what does a business learn from it?
- State the difference between a job description and a person specification.
- Name three selection methods and say what each one shows about a candidate.
- Why do most businesses use more than one selection method?
4.2.1c Benefits of effective recruitment
What makes recruitment effective
Effective recruitment and selection: a process that attracts enough suitable applicants and then reliably appoints the one who best matches the person specification.
- Every benefit in this topic starts from the same cause: the person appointed can actually do the job, so the business ends up with the right person in the right role.
- An effective process is not the cheapest one. Aldi paying for an online test and an interview spends more up front than a manager skimming a pile of CVs, but is far more likely to appoint somebody who can do the work and who stays.
- The gains show up in three places: how much staff produce, the quality of the product or the service customers receive, and how long employees stay.
Trace each benefit through to the business instead of jumping to profit, so write that output per worker rises, therefore the cost of making each unit falls, therefore the business can undercut a rival.
Higher productivity
- Somebody selected because they have the skills the job needs works at full speed sooner and needs less supervision than somebody appointed only because nobody better applied.
- More output from the same wage bill lowers the cost of producing each unit, so the business can charge a competitive price or keep a wider profit margin on the price it already charges.
- Managers also spend less time correcting work and chasing progress, so they can get on with their own responsibilities rather than covering for a weak appointment.
At Nissan Sunderland an assembly worker chosen with a practical test reaches full line speed within days, so the plant builds more cars per shift without paying any more in wages.
Higher quality output and better customer service
- Capable staff make fewer mistakes, so less material is scrapped and less work has to be done twice, which cuts waste and the cost that goes with it.
- Fewer faults reaching customers means fewer returns, refunds and complaints to handle, and a reputation for quality that lets the business hold its price.
- In a job that involves dealing with people, the right appointment shows straight away, because a patient and cheerful assistant on a Currys shop floor explains the product properly and sells more.
- Good service brings repeat custom and positive reviews or word of mouth, so sales rise without the business spending more on advertising.
Greggs selects counter staff partly on how they handle a queue, because a fast and friendly counter is what brings customers back at lunchtime.
Staff retention and lower training costs
Labour turnover: the rate at which employees leave a business and have to be replaced over a period of time.
- Somebody whose skills and personality suit the job is more satisfied in it, so fewer new starters walk out in the first few weeks and labour turnover falls.
- Recruiting less often saves the money spent on adverts and agency fees and the paid management hours that shortlisting and interviewing take up.
- There is less retraining to pay for, because the business is not putting a new starter through induction every few months, and it keeps the experience staff have built up.
- Existing employees gain as well, since they are not constantly covering empty posts or training replacements, so their own work and motivation do not suffer.
The same argument works in reverse: a poor appointment leaves the business advertising, selecting and training for one post twice over, and losing output in between.
- For analyse the benefits to the business of an effective recruitment and selection process, start from the right person being appointed and take each step through to an outcome such as lower unit costs.
- Pick the benefit that fits the business given to you: productivity for a manufacturer such as JCB, customer service for a restaurant or a shop.
- Use the terms productivity, labour turnover and retention precisely, because they are what the question is testing.
- What makes a recruitment and selection process effective?
- Explain the chain from a good appointment to lower unit costs.
- How does appointing the right person improve customer service?
- Define labour turnover and say why effective selection lowers it.
- Name two costs a business avoids when its staff stay longer.
4.2.2 Contracts of employment
Contracts of employment
Contract of employment: a legal agreement between an employer and an employee setting out the hours, pay and conditions of the job.
- The contract states the job title and duties, the hours, the rate of pay, holiday entitlement and how much notice each side must give, so both know where they stand if there is a dispute.
- The type of contract offered decides how many hours are guaranteed, which is what separates full-time, part-time, job share and zero-hours arrangements.
- A business uses a mix of contracts so that the number of staff on site matches the number of customers, because paying employees to stand idle wastes money.
An employer must give a written statement of the main terms, including pay, hours and holiday, on or before the employee's first day of work.
Full-time contracts
- What it is: the employee works the business's standard week, usually around 35 to 40 hours, and the same hours are worked every week.
- Benefits to the business: the same person is there all week, so they learn the business thoroughly, customers deal with a familiar face, and training is worth paying for because it is spread over more hours worked.
- Benefits to the employee: pay is predictable, which makes it possible to budget or take on a mortgage, and full-timers usually get first claim on training and promotion.
- Drawbacks: the wage has to be paid even in a quiet week, so it is a cost the business cannot switch off, and the employee has less time left for study or family.
A Warburtons bakery keeps its production staff on full-time contracts, because the ovens run to the same schedule every week and the business wants the same trained people operating them.
Part-time contracts
Part-time contract: an agreement to work a set number of hours that is fewer than the business's standard full working week.
- The hours are agreed in advance, so a part-timer working Thursday and Friday knows those shifts are theirs every week.
- Benefits to the business: staffing can be pointed at the busy hours rather than spread evenly, opening hours can be extended without paying anyone overtime, and more people apply, including parents and students who cannot work full time.
- Benefits to the employee: work fits around childcare, college or another job, and part-timers still get holiday and other rights in proportion to the hours they work.
- Drawbacks: the employee earns less and can be passed over for promotion, while the business has more people to train and manage for the same total hours and has to hand work over between shifts.
Tesco covers its Saturday peak with part-time staff, so it is not paying for extra checkout hours on a quiet Tuesday morning, and students earn without missing college.
Job share
Job share: an arrangement where two employees split the hours, duties and pay of one full-time post between them.
- One sharer might work Monday to Wednesday and the other Thursday and Friday, so the post is filled all week even though neither person works full time.
- The business gets two sets of skills for one job, keeps the role covered when one sharer is ill or on holiday, and can hold on to an experienced employee who no longer wants full-time hours, which is why job shares are common in the NHS.
- It only works if the two hand over properly, because anything one of them leaves half finished has to be picked up by somebody who was not there.
Zero-hours contracts
Zero-hours contract: a contract that guarantees no minimum hours, so the employer offers work only when there is work to be done.
- Benefit to the business: it pays for the hours it actually uses, so wage costs rise and fall with demand, which suits work that cannot be predicted, such as catering at a stadium or courier work for Deliveroo.
- Drawback to the business: workers can turn shifts down, so nobody may be available on a busy night, and because they leave as soon as steadier work appears, the business is forever training replacements.
- Benefit to the employee: hours can be refused, which suits somebody fitting work around a course or another job, and every hour worked is paid at least the national minimum wage.
- Drawback to the employee: income swings from one week to the next with no guarantee of any, which makes it hard to budget or get a loan, so the flexibility the business gains is exactly the security the worker gives up.
- Part-time and zero-hours are not the same: a part-timer has agreed set hours each week, while a zero-hours worker is only offered hours when the business wants them.
- Zero-hours workers are not unpaid, and they are not self-employed; they are paid for every hour they work.
- For explain one benefit to the business of employing part-time staff, give the benefit and its consequence, such as covering the weekend rush without paying wages through a quiet weekday.
- Check whether the question asks about the business or the employee, because the same contract looks completely different from each side.
- Use any demand pattern you are given: steady year-round work points to full-time contracts, an unpredictable rush points to flexible hours.
- What is the difference between a full-time and a part-time contract?
- Give one benefit of full-time employment to the business and one to the employee.
- Give one benefit of part-time employment to the business and one to the employee.
- What is a job share, and what has to happen between the two sharers for it to work?
- State the trade-off in a zero-hours contract between the business and the worker.
