That's a good read. Just goes to show that it's important to remember people's humanity, especially when all the cards are stacked against them. People have said some really ugly stuff about MM.
And execs get paid for the expectations and responsibility. You are just being salty right now.
I worked as a engineer at a huge billion dollar company in a newly created slot. There was 2 on the team and I was the third. Then massive layoffs. Thousands of people let go. I was one of them. Was I "good people" ? I don't know. I like to think I was, that's why I got the position. Of the 3 people on the team, I was the right choice though, least experience with the company's infrastructure, etc.
The real issue at hand was the disconnect between the team manager (who found out he had to let me go the morning it happened and was quite upset about it) and upper executives. Why was adding my position approved by upper executives in the first place if they knew that a month later they would be laying off so many, you would think they would have had a massive layoff of that size in the works for more than just a few days.
So there was no "good reason" other than "cutting cost" but if someone had to be let go, the 2 others on the team deserved the job more than me.
You were clearly good enough to get hired but all things considered you were the correct person the let go.
The distinction, and you seem to understand, is that it wasn't a personal thing. People say stuff like "let go of good people". What does being a good person have anything to do with running a business?
Not saying any of this is right or wrong but more musing over what drives business decisions and how people will often mix personal feelings into non-personal decisions.
