I was just put on a performance improvement plan myself a couple weeks ago (looking for other jobs since). It sucks, and I still struggle with this myself, but trying to remember that my ability to perform in this awful system is not a reflection of my character
While there is some merit to looking at how a team performs and how this can be improved, this is not always the case. My experience with this as a worker and (previously) a supervisory position showed me that the bar for performance will always be raised.
You could be performing just as well or better than people previously in your position, but managers and capitalists will almost always push for more from you. Most think they need constant improvement and growth to justify their position and that of their teams and there can be a very real threat of losing your job because of this.
Just remember that your worth as a human is not tied to your job performance and the system you live in will always be squeezing you for more. You are not a robot. You are not a computer. Humans have limits and pushing yourself past those limits comes at the expense of the quality of your life.
Capitalism necessitates the exploitation of resources, including those of your body in the form of your physical and mental health. Do what you can to maintain stability and financial security in your life, but I suggest looking for work elsewhere if possible.
Why? You’re doing less work you’re the smart one
You’re colleagues should slow tf down. What’s wrong with them?
Don’t feel stupid. Capitalism is not set up to get the best out of people, and the effects of this have no bearing on your worth.
Have you been in your job/role for long?
3 years now 🥲, but many of my colleagues have double digit years of experience. I only have those 3 in my area. In fact this was my first job out of college
While I think you should always be open to finding new ways to do your job, it is noteworthy that you managed to stay 3 years at the place while ‘underperforming’ as you say. You’re very likely doing better than you think. And comparing yourself to people who have double digits years of experience is unfair. Have they ever mentioned something about it?
Studying one’s performance should not be something that one gets by looking at the people around themselves, but by looking at one’s past and one’s present. Give yourself time, you can do it.
