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.
