I do not think the covid19 tag should be destroyed since it is very likely that someone else will just recreate it with a new question.
I want to remind everybody that we already have a health tag, that applies perfectly to this situation (one's physical health in the workplace).
Personally, I would advice on considering using the health tag instead, if the case is fit (where the answers could be applied to health in general).
Besides, I advice to be aware of posts where the covid-19 tag was included, but the question and core issue are something completely unrelated to health or covid. Or where other more relevant tags were left out.
For example (out of my mind), cases like: Communicating something to a colleague or boss via email, in the Uk, because X thing happened... because Y thing happened on project Z... because covid...
We can see that here the core tag should be communication, and other related tags would be colleague, management, software-development perhaps, email perhaps also, and so forth... The answers that post would get would surely be useful and work regardless of the Covid situation; some other reader that also needs to send that email would find the answers useful in a future even though Covid is no longer around. Cases like these is where the covid-19 should not be (ab)used.
Now, in any other case where Covid is intrinsic to the issue or question (and is NOT asking for medical or legal advise) the tag applies.
