"Non-essential". That sounds like a public sector classification.
It's a polite way if saying "if you're not saving lives, stay the **** off the roads." Of course, every employer I've ever had thinks we are essential. I've never had an "essential" job. Police, fire, rescue, ER, nursing home and hospital staff
I work on the University side of Duke. Compared to the medical center side, I’m very non-essential.
