Refusal to employ on grounds of trade union membership/non-membership Within three months of the date of the conduct to which the complaint relates (s.139 of the TULR(C)A)1

From 6 May 2014 (or from 6 April 2014 where the prospective claimant voluntarily contacts Acas under the early conciliation procedure) the time limits are extended to take account of the early conciliation procedure. The period beginning with the day after the employee first contacted Acas under the early conciliation procedure and ending with the day he or she receives the early conciliation certificate will not count when calculating the time limit for bringing the claim. If the limitation period would have expired during the period starting with the day the employee first contacted Acas and ending one month after he or she receives the early conciliation certificate, it will be extended to expire one month after receipt of the early conciliation certificate.
