@GottaLaff Social media is voluntary. You can post or not post whatever the hell you want People who feel like the get to tell you what to post or not post have serious entitlement and control issues.
Maybe next time tell them, "Thank you for the job offer. Here's what I want you to pay me, & these are the benefits you'll provide. Then once I agree to work with you, you'll have some right to tell me how to post."
