Make a Run for It

I quit my job today.

After a meeting in which I was treated like a child and given a "final warning" for shoddy attendance. I walked out--typed up a letter of resignation--printed it in triplicate and QUIT.

My boss called me in and pretty much talked me out of it. She painted mirages of permanent employee status (I'm a consultant now--no paid vaca) and a signing bonus with a raise attached (not to mention German Bank-paid dental coverage).

Now, I have tonight to "sleep on it" and give her my final answer. Can one renege on a resignation? I mean...it's in writing!
