Pros: the clients are great
Cons: horrible management
I worked at Regus for a little over three years as a Client Service Representative and I do not recommend this company. I was shocked to learn that the duration of my employment was a record within that location due to the high rates of turnover in the company. In just my location, we went through (off the top of my head) at least six staff changes due to firings or resignations. Of course, the only staff that never changed were the two management positions, who treated the staff poorly. My direct boss exhibited inappropriate behaviors all the time towards the staff and the clients, both of whom were ignored if they complained in reviews or to management. This also greatly fuels the turnover.
Oh, and all of those "promotions" and "opportunities for learning new skills" they touted at my interview NEVER came about. Actually, how it works is unless the person above you retires/resigns or you are willing to move to another city, you won't get promoted.
Only work for Regus if you really need the income, but continue to actively look until you can get another position.
