Evaluate, using appropriate diagrams and the information in Extract B, the extent to which trade unions are responsible for market failure in labour markets.
One of the most significant operational costs faced by offshore wind farm operators and oil giants is the hire of specialized Subsea Remotely Operated Vehicle (ROV) pilots. These highly skilled technicians have secured double-digit wage increases for five consecutive years. Trade unions, such as the Offshore Mariners' Union (OMU), hold a formidable position in wage negotiations in the North Sea. Between 2013 and 2023, over 35,000 technician-hours were lost to wildcat strikes and coordinated walkouts over safety protocols, shift rotations, and automated subsea piloting systems. Industry watchdogs argue that union collective bargaining has pushed salaries for experienced ROV pilots to £84,000 in 2023—well above their marginal revenue product of labour (MRPLMRP_LMRPL), and nearly triple the national median.
However, the union defends these salaries, pointing out the immense cognitive load and physical toll of the job. Pilots operate multi-million-pound subsea vehicles in pitch-black, high-pressure ocean trenches, managing complex environmental risks under nuclear maritime regulations, and working grueling 3-week offshore rotations. Furthermore, the union argues that collective bargaining is the only defense workers have against the oligopsonistic power of the massive state-backed energy cartels that dominate the offshore sector.
Despite these localized successes, union power across the broader energy and maritime sector has dwindled. In the early 1990s, union density in maritime support roles was nearly 60%, but has plunged to less than 18% today. This decline, driven by subcontracting, digital simulation training, and international crew sourcing, means that union-led wage distortion is increasingly confined to niche, high-skill bottleneck occupations.
