Salam alaykum, It's very difficult to work in an environment like that. I have worked in environments like that and it is very unpleasant. The best method is to go into work, keep yourself to yourself, do what you gotta do to the best of your ability and go home. Leave work at work. Get on with your life. Pray to Allah (swt) to give you patience to deal with their horrible akhlaq because sometimes it is very hard to hold back. Try finding a better job but until you don't, best of luck. Ma'assalama
