One on the things we contract workers at Atch.Pee.have been doing is watching the phone book. The HP online "people finder" phone listing includes office location, department, manager, and if your a "contingent worker" it not only says that but it says when your contract is due to expire. Generally this is set at 2 years from when you're hired. This week mine was changed from 4-27-2010 to 11-27-2008.
Makes me think longingly of just being the village sandwich-maker.
