Evaluate, using an appropriate diagram(s) and the information in Extract A, the extent to which trade unions are responsible for market failure in labour markets.
One of the most critical operational costs for offshore marine engineering contractors is the remuneration of Remote Operated Vehicle (ROV) senior pilots. These pilots have secured substantial real wage growth over the past decade. Trade unions maintain a highly consolidated position in collective bargaining across North Sea operations. Between 2013 and 2023, more than 35,000 offshore man-hours were lost to industrial action at major energy hubs, with crew striking over safety-critical shift rotations, pension contributions, and the deployment of autonomous deep-sea drones. Industry critics argue that union-backed wage floors have pushed annual salaries for senior ROV pilots to over £85,000—nearly 2.5 times the national median—far exceeding their estimated marginal revenue product (MRPLMRP_LMRPL) during periods of stable energy prices.
However, maritime union representatives defend these wages, citing the extreme environmental hazards, prolonged isolation on offshore rigs, and the immense responsibility of operating subsea equipment valued at up to £15 million. They argue that without collective wage-setting, highly concentrated offshore energy consortia would leverage their monopsonistic buyer power to exploit specialised technical staff, suppressing wages well below competitive levels.
While unions retain significant leverage in these specialised, high-skill offshore niches, their wider industrial influence across the energy and maritime sector has diminished. Across the broader offshore support and logistics industries, union density fell from approximately 45% in 1995 to below 12% by 2023. This structural decline, driven by outsourcing and international crew contracting, means that aggressive wage-intervention capabilities are now concentrated in only a small number of critical, high-barrier-to-entry marine engineering roles.
