The Employment Act 1990 is an act of the Parliament of the United Kingdom.
The act, a piece of industrial relations legislation, banned closed shops, which had already been restricted by the Employment Act 1982 by requiring 80-85% to support them (such an impractical requirement that they had been effectively almost banned). It also banned secondary action in industrial disputes, again building on restrictions on that form of picketing introduced by the Employment Act 1980.
