Why do I have to sit through these pointless meetings each week at work? 😒

I just consider it part of the job.

It's this way: they're buying time from me, X hours a day. If they want to use that time to have me editing documents, great. They're getting their money's worth.

If they want to use that time to have me sitting in meetings or otherwise underemployed? They bought the time from me. It's up to them how they want to use it. If they want to pay a writer-editor's salary to have me sit in meetings.....that's their choice.
