Warehouse/assembly line/blue-collar job life ain't always pretty, to say the least. My son-in-law works an assembly line job in Birmingham, and the hours, expectations, and demands are well beyond absurd (I guess they get around the legalities through a lot of "voluntelling"). So, I'm not surprised a bunch of low-wage workers were expected to work all night even with a moderate risk in place and a large, confirmed tornado barreling toward Mayfield for well over an hour in advance. Which could maybe speak to the argument that wording with these outlooks needs to change. A moderate risk doesn't sound threatening. Level 4 out of 5 sounds much more serious.
