The simplest explanation for why your performance ratings have been declining is that your performance is declining.
When you’re not railing against workplace diversity, ESG, or proclaiming that your human rights are being violated by office layouts, you’re generally accomplishing nothing of added value.
Very few of you have evolved your skills and knowledge base to include anything that isn’t from the previous decade. Almost none of you have adjusted to the culture of the modern workforce.
Bottom line: you’re not nearly as valuable or competent as you think yourselves to be. You need to own that.
