Lots of people were asking to do an update when I gave my employer my two weeks notice, so here it is:
I wrote an email to my boss, the department head, and HR letting them know my last day. Let me tell you, their reaction was incredibly satisfying!! Funny enough, a position “suddenly” opened up for me. I eventually caved and told them how much my new job is paying me because they really wanted to make a counter offer and his response was “never mind. congrats”. No one is bugging me about it anymore and I still get to continue working for two weeks. I did not disclose the company I am moving to, as I am still waiting for my background check to clear, and I don't want my employer calling them up and lying about the quality of my work to force me to stay.
