The headquarters has an elevator, so there is no need to take the stairs.

Departments related to $$ are not very good. You may become the target of office politics, so you need to be very careful not to offend anyone. It is troublesome, and in the long run, it is also not very good because you are very likely to offend someone eventually and become singled out. It is somewhat exhausting; please handle interpersonal relationships with extreme caution.
