It's ironic, in a way. I was in an abusive work environment, with abusive clients, and had to dream up ways to efficiently do the job of three people. It was awful and I was there for over a decade trying to get out, but the methods I invented to make my hellish job easier helped me get hired where I am now.
Two weeks before I left I'm walking into work and I get the call that I've been hired to the job I have now, which has a much better culture and reasonable work load. I was so happy I skipped to work Dick Van Dyke-style and immediately put in my two weeks.
Had a replacement plan done in two days because I already had my tasks inventoried, since I had to keep very close track of my productivity to protect myself from HR and management. I had some tenure and was making more than other employees, and therefore a consistent target for layoffs.
Spent the last week and a half getting paid to do jack shit, though my asshole team did make me take my turn with the on-call pager, even though it made no fucking sense other than spite.
Overall, t'was glorious.
