If I read this correctly, the ex-Major has only been in the job one month and he is already berating smartly dressed employees with abusive insults such as the tranny suggestion, yet he turns up at work in a tee-shirt, cargoes and sneakers. Worth discussing with your co-workers to see if they have been having similar problems with him finding other excuses to berate them and then take a joint grievance to the top manager. The way the Major spoke to you displays a clear lack of management skills and I am confident he will not last long in this job once the top man susses out his chronic inadequacy. Well done on the restraint shown on the day.
