Hi Greenshade,
Looks like you have two possible ways of dealing with new workspace:
1) Accept it for what it is. Remember that it only temporary and you’ll be moving on. Whenever you see someone exhibit perfectionist tendencies, say to yourself (silently or aloud), “not mine”, and go about your day the best you can and focus on the things you do enjoy.
2) Make a change. This can be as drastic as leaving the job entirely, or ask to be transferred to another department/project. Even if the general culture is very Type A, you’ll always find pockets of like minded Type Bs in any organization. Find out who those people are and see if you can work with them instead.
Hope that helps!
