Problem
Many employers now operate using a combination of full-time employees and contract workers. From the employers' perspective, this allows for greater flexibility, and gives people who don't want to work full-time an opportunity to contribute. On the other hand, this arrangement may also be seen as creating a hierarchy in which the full-time employees earn better pay and benefits while the contract workers don't share equally in the prosperity. From the standpoint of equity, are companies that rely heavily on contractors treating all their workers fairly?
