"The Tribunal accepts that the applicant was disappointed when he failed driver training and clearly bore a grievance against the training staff at Waterloo. He was clearly upset when he reported to Mr Baker, the Area Train Crew Manager on 12 March and asked to take some leave in order that he could have time to sort out his future. He was granted two weeks' leave by Mr Baker and this was subsequently extended at the applicant's request by Mr Baker's assistant for a further two weeks expiring on 7 April."
