The UK's Private Security Industry: A Study of Trade Union Issues Available to Purchase

The UK's private security industry is an employer of substantial magnitude. APEX (1991) claim 30,000 members in this industry. Calculations of trade union penetration in this sector are difficult because data on the industry is very patchy. APEX have quoted an estimate of approximately 100,000 employees, but other estimates suggest the figure is much higher, perhaps as many as a quarter of a million.
