You are incorrect, I bet you're middle-management. A boss that doesn't respect his employees can't expect that employ to bee "concerned about the workplace" lmao. Work is a big act for many people, they make the manager feel good and respected for 8 hours a day but behind their backs rarely respect them, particularly ones like this.
The boss created the initial health hazard, and I hope someone sick sneezes on you soon to prove this point.
