I had access to the Trans States Employee Website for almost a year after I quit that job.

Also, on a more serious security note, it took them (Trans States) almost 6 months (and a lot of nagging) to take my personal ID code out of the SIDA system at OHare after I quit.. as far as they knew, I could have not been in the airline business any more, but still had access to the ramp any time I wanted.. haha.. just more fun in the Hulas system..
