This feels fake. I could be wrong and hope I am.
No manager competent enough to write that well is going to put anything like that down in writing. Totally fake.

I worked for an IT manager who fired me after I pointed out that he was scammed for buying a 6 pack 1TB flash drives from Amazon for $40.

He wrote an email saying I was a jerk for delegitimizing his authority which I took to HR and was fired the next day “for not being a good culture fit” and was paid to be under a nondisclosure for half a year.

I am like Mulder, I believe the morons are out there.
