Employees appointed by trade unions to represent the interests of their colleagues regarding their health, safety, and welfare at work. Regulations made under the Health and Safety at Work Act 1974 give a trade union recognized as having negotiating rights on behalf of a group or class of employees the right to appoint at least one of those employees as a safety representative. The representatives' statutory powers include the investigation of accidents and industrial diseases occurring at the workplace and inspection of the premises to determine their causes. The employer must allow them time off work with pay to train for and perform their duties and to attend meetings of safety committees. See also disclosure of information.
