haha sucks man

That's a really shitty thing to do to someone; I'm sorry. Is there any way you could get him to speak to your boss and clear things up, or something? ETA: Somehow I missed the part that it was a CO-WORKER when I first read this. That's even worse! He really should be disciplined for that. VERY unprofessional and childish.

I feel really bad

Yeah.. Ur "FRIEND"..

if you get an email saying your fired, and you beleived it, you must be dumb

if you saved the email then you can appeal it... just saying

Adam Jensen?? You should just stab your co-worker with your augmentations dude

He or she obviously wanted you out. Pretty messed up :/ On a side note, OP has a badass name haha. I love Deus Ex

This is when you immediately print the emails and go to your HR department and demand to know if its true.

Failed.
