Section 100 of the ERA 1996 (as amended) states that “if the reason (or, if more than one, the principal reason) for the dismissal… is … being a representative of workers on matters of health and safety at work or member of a safety committee”, that dismissal is unfair. Unlike most claims for unfair dismissal, no set period of service is required to bring a claim if the reason or main reason for dismissal was being a safety rep. Dismissal for this reason is “automatically unfair”. In other words, as long as the employee can show that the main reason for dismissal was being a safety rep or a member of a safety committee, the dismissal will be unfair. The employer will not be allowed to argue before an employment tribunal that the decision to dismiss for that reason was “reasonable”.
