The Trade Boards Act 1909 created four Trades Boards that set minimum wages which varied between industries for a number of sectors where "sweating" was generally regarded as a problem and where collective bargaining was not well established. This system was extended considerably after the Second World War; in 1945 Trades Boards became Wages Councils, which set minimum wage standards in many sectors of the economy, including the service sector as well as manufacturing. Wages Councils were finally abolished in 1993, having fallen into decline due, in large part, to Trades Union opposition. A lower limit of pay, or "pay floor" was regarded as threatening the voluntary system of collective bargaining favoured in the UK. The government had first made a serious attempt to abolish Wages Councils in 1986, having abandoned existing legislation that tried to widen the scope of voluntary agreements to include those firms that had not taken part in negotiations, such as the Fair Wages Resolutions. These required that government contractors pay fair wages and respect the rights of their employees to be members of trades unions.
