Teachers and students work together to identify areas of interest and need, and teachers offer a variety of options for students to choose from on Fridays.
In a work environment it could be used as a term for various ways to work outside the normal 8-5 window, or telecommute. It might involved compressing the week and having Friday off, or it might mean different hours on Friday, or working from home.
Have you ever worked in a flexible environment?
I spent 25 years at Hewlett-Packard working various schedules and I loved that company back in the "golden era" of it's day.

This picture was yesterday at the gym, I didn't really mean to hide my face but I felt my flex coming back!! I'm smiling!
Who else thinks Flex Friday is fun for any reason at all? Or gives you a reason to smile?
