Doing the math

INSUBCONTINENT EXCLUSIVE:
Pilot fish is interviewing for an IT job when he learns that many of the company's top technical staffers are actually consultants."These
were primary technical staff, the subject matter experts," says fish
"Most companies prefer to staff those types of positions with permanent employees due to their importance to the organization with the
knowledge they have, so I asked about that."I was told that those consultants had been employees there at one time, and chose to switch over
to hourly employees."This seemed strange to me, being fairly early in my career and not having a deep breadth of knowledge of how
organizations work
They seemed to have decent benefits -- why would anyone want to give them up
