At my job they let go of about ~30% of the work force around one year ago. I knew that this theoretically could happen, but this was the first time seeing it myself.

And I am left thinking, if in the future I see a coworker leave on the day by his own choice. I wouldn’t hold it against him. The company has shown how easily they are willing to let go of a huge number of people. Why should I be mad at any of my coworkers if they decide to leave on the day? The company already set the bar for how this works.
