I need to be talked out of resigning. It would be very unwise of me to resign as I will (hopefully) be going on adoption leave in a few months and not going back. If I resign now I will miss out on various things while I'm on leave, like non-contributory pension, health insurance, statutory adoption pay.
But I am unusually pissed off with work. Someone in my team gave an exec my mobile phone number. It's my private mobile, I don't have or need a work one. I don't work on Wednesdays. And to top it off it wasn't even one of the nice execs that I get on with, it was someone that everyone in the team knows can be a pain in the neck.
I sent a snotty email, but fortunately (or not) went through it again and took out most of the swearing and the flouncy "I quit" statement. I still feel like quiting though.
