If you work for a division of a company then do you technically work under the name of the division or the company itself? I'm not talking about departments, such as finance or accounting or management, but actual divisions with different names (as if its a stand-alone company). I am not sure but I believe a division in this case is also called a subsidiary. A good example is Parke Davis, which is now a division of Pfizer. So, would a person be working for Parke Davis or for Pfizer?

Does each division have its own set of unique rules, regulations, and policies or does it use company's rules, regulations, and policies? Or does it depend on the acquisition/merger contract?
