Well I don't think someone adapting to new disabilities or impairments should be punished for it. So if someone is getting PIP'd a few months after returning from covid and aren't performing, I think theres a lot of moral failings as a manager/owner/employer you can have if you don't take it into account.

Also, why is it wrong to want to provide grace to those dealing with it? Like suddenly losing IQ or getting a cognitive impairment is a huge part of someone's life, there are non-invasive and non-condescending ways to support them
