Weird to put that on the employees if you ask me. It's not like there is exactly 13% of bad employees. Or 25% of bad employees but they decide to just fire 13% for some reason.

To me, it seems quite evident, they need to reduce the spending for any reason, so they reduce the workforce. Nothing to do with useless employees. You can be shit at your job or very good, they will have a metric threshold telling them you need to go. Same at Twitter, Meta, Google, whatever.

Stop putting that on the employee who spent 3 months to get a job just to be told they wasn't useful. That's 'bad' managing all the way down, nothing to do with the employee, at all.
