One company I worked for handed me their non-compete agreement. It said if I ever left the company, I agreed not to work in any tech company for a year.
I said I could not sign that as I had family to feed.
Oh, he said, here’s a different agreement – and pulled a different from out from the files. This one was limited to the specific tech of projects I worked on. Heh.
Since this was a huge company that did tech in many fields, the first policy would have effectively meant I could not work anywhere.
