This is from a friend of mine that gave me full permission to post.
I used to work at a community college that I left due to a hostile work environment. We had a great many permanent part-time workers that were never allowed to go over 19 hours a week. If they hit 20 hours a week that would push them into full time, which meant the college would have to start offering them insurance and benefits.
The college decided to do an audit of the part-time workers and discovered that one department (the workers there had initially been hired under a different category that was later changed to the permanent part-time category) were being overpaid.
They yanked fifty cents an hour away from those employees, from 9.00 an hour to 8.50. Yep, the college saved themselves ten dollars a week!
