Being forced to wear un-Islamic clothes to work

Q: I have to go to work in Saudi Arabia. They are saying that I should dress casual, that means pants and shirt. I don't like to wear it as I prefer a thobe and red guthra. What should I do? Some of the people laugh and say - molvi got sold out for money - wearing pants and shirt - showing his privates around. Some say you are caught into the trap of the enemies of Islam and shaytan. I sometimes hear such comments and as a result I don't know what to do?

1. Is it haram to do like this - wear pants and shirt for work only and then dispose of it after work?

2. Is a tie a sign of the cross? Everyone at work wears it except me and a few others?

3. I am scared that if I die in this condition will I go to hell for earning rizq in a haram way i.e. wearing pants and shirt?

4. I am thinking how can I convince my non-Muslim boss to allow me not to wear it especially when everyone is ok wearing a business suit?
