Second, the Industrial Relations Act of 1971, introduced by Robert Carr (Minister of Labour in Edward Heath`s office), provided that collective agreements were binding unless a written contractual clause provided otherwise. After the death of the Heath government, the law was rescinded to reflect the tradition of British industrial relations policy to legally refrain from any conflict in the workplace. When collective bargaining results in an agreement, for example on a wage increase or a change in working conditions, it is called a “collective agreement”. Negotiations are conducted by trade unions and employers. The trade union side may consist of full-time civil servants, company representatives or a mixture of both. Local union representatives are now much more likely to participate in collective bargaining.
