in most countries around europe, different forms board representation law spread slowly, especially from the 1970s. in the uk there were repeated experiments from iron and steel to the post office, with worker directors. however, after the bullock report of 1977 failed to pass and margaret thatcher won the 1979 election, almost all worker participation was ended. germany recast and extended its laws in 1972 and 1976. the european commission did propose a draft fifth company law directive, but it did not complete passage. in the united states, growing interest in worker "involvement" through scanlon plans led to unions such as the united steelworkers at chrysler, or at united airlines to negotiate board representation, although usually this was forcibly linked to employee share schemes. notably, the share scheme at enron failed in 2003. almost all modern worker representation laws enable votes without any requirement to invest money. in 2013, france became the largest country to create a modern board representation law to mandate workers with equal rights to all other directors to be on boards.
