There are some differences, however. Work hours are dictated by the hours of the facility, not by the government client (with the exception of shift employees, such as security, whose rosters are controlled by their companies). Government employees aren't permitted to direct work of contractors; they have to go through the contracting officer who then contacts the contracting company's manager for all requests. Part of the contracts' language specifies interchangeability of personnel (as long as they are similarly qualified and possess the necessary clearances). And the contractors are employees of the company awarded the contract. If you had a different experience than that, then your former office is at serious risk of a lawsuit.
