Glad you got fired. Vaccines should always be mandatory save for legitimate, doctor-validated medical exemptions.
Anti-vaxxers are fucking stupid and should either be educated properly or, if they still refuse to do their civic duty after being de-programmed of misinformation, punished. You are only allowed to participate in society if you take the necessary steps that you are morally and ethically obligated to do in order to protect it from preventable, transmissible disease. We had eradicated polio until stupid motherfuckers like yourself decided that it would be a good idea to forgo the standard polio vaccine schedule that we've had for decades. Now, we saw the first case in 30 years in 2022 because someone selfishly thought that their personal beliefs were more important than the health and livelihood of everyone else.
Thank God someone else said it. I was constantly in an existential battle with IT at my last job when they were constantly forcing updates, many of which did actually break systems we rely on because Apple loves introducing breaking changes in OS updates (like completely fucking up how dynamic libraries work).
Updates should be vetted. It's a pain in the ass to do because companies never provide an easy way to rollback, but this really should be standard practice.
