My old company did not take my departure with such grace.
I started looking after I observed another department treat an employee with a disability unfairly, resulting in a reduction to 4 hours of work per week, and them forgetting to submit her timesheet. I escalated the issue all the way up to the CEO, who responded “the lawyers said we did nothing wrong”.
I started looking at that point and found a place with 1/3 of the responsibilities, and which paid at the top end of my market rate. I didn’t even give them the option to counter.
It’s been almost 2 months and they still haven’t found a replacement. I told them could maintain the system as a freelancer, but they haven’t taken me up on it.
