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.
