BTW, your reply is inappropriate and unprofessional.
Sorry for your experience. You should have enlisted our help, we could have helped make changes with you. Management and union can be quite effective together. But you took the easy way out and left. If it was truly that bad for your employees, who is left there to fight for them. Sounds like you wimped out to me, what is what most ineffective managers do. Congratualtions, i bet you got a promotion when you left.
