Avantages
None unless you are part of their corporate mindset. If you tow the line like a good little lemming, then you are a model employee. If you are a protagonist, point out what could be done differently, then you are not a "team" player.
Inconvénients
To much one way thinking. When it was the Frick Company, it was very hierarchical. If you were a Claims Service Representative, you were the bottom of the barrel. You were seen and treated that way. I had a BS in Business Administration, put together a position paper, sent it up the chain and one Senior Manager stated that he was surprised that a CSR knew so much and could speak so formally. I had more managerial experience than my own supervisor, I just didn't have the practical experience. Then TALX bought us out and then the culture changed for the better. Equifax then bought us out and things more or less stayed the same. Then we got a new manager and things went back to that hierarchical structure. It became the worst place to work. Everyone became fearful and then 1/3 of the people got laid off and 1/3 got transferred.
