My last job I had to pull HDDs from the all in one Mac desktops.
If the screens had been removed to upgrade the hardware previously, it was a major pain in the ass to remove because the adhesive to reattach them was much stronger than the OEM.
So, knowing how to do things properly, I asked where the heat gun was. My boss said, "You can't use a heat gun. Just hit the screen with a hammer until it comes off." I had already been hit close to my eye by flying glass from removing them normally at that point, and they didn't provide eye protection.
That's when I said they had a choice. I'd be using a heat gun, not removing the screens, or having a discussion with the safety office. It was my last week (90 day temp), so my boss said, "Fine, I'll do it myself."
