The Unite general union’s rule book says that at each workplace, the members employed at that workplace, shall elect from among themselves, at least every three years, one or more of the following representatives: shop stewards or workplace representatives; safety representatives; learning representatives; equality representatives; and environment representatives. The election shall take place at a meeting held between 1 January and 31 March in each third year. Election to one representative role does not preclude election to another such role within the same workplace.
