Gah - plans have changed. Instead of leaving at the end of August (early August with all my banked holidays), I've agreed to leave at the end of December. Due to stupidity in government hiring processes, we can't fill the 3 of 4 current vacancies until September. If I left, there would literally be no one left in the department.
Not my problem, I know. However, the friend who got me the position, literally by telling HR I was the only one she would hire out of a pool of strong candidates, is now the manager of the team. I don't want to leave her in the lurch, so a few more months isn't a hardship. Hubby and I will be taking our planned trip to Europe in October, so the only real hassle for me is having fewer days off to get the house packed up, and move to our new home in another province.
At least I'm still in the 2018 cohort! No OMY syndrome for me!
