stand your ground. Ask for reasons why they won't allow it and ask for proof of anything they bring up. ask why they want you to change location. Keep a record of the conversation including who was present.

Don't be afraid to say "I feel like you are trying to pressure me into this relocation of employment. I am not happy with the relocation or the new hours due to xyz (remove emotion)". Avoid the use of the word bully unless you REALLY need it. Make sure you stay calm and do not use emotion.

Sorry for dot points.
