Genentech is hailed as one of the greatest places to work. An asterix should be added to that as that only applies to employees and huge percentage (guessing at least 30 percent and growing) of the workforce there is contracted out or temps.
Genentech treats contractors so poorly and the proportion of contractors is way too high especially for advanced level work that is not needed for a temporary basis.
They never get recognized even though they do most of the work, pay is horrible, have to pay for corporate buses, are not invited to department meetings or celebrations, and the contractor parking lot is at a undesirable warehouse location 15 minutes away even though permanent employee parking always has available spaces. I have not seen so much segregation in a corporation.
As a contractor for 3 years there I've seen countless advanced positions which should be designated for permanent employees go to contractors for half the pay. Most of these contractors end up never getting hired even though they perform well often. Most I see leave in less than a year.
