Also, are the towers still dark so they can see the screens? That can make you sleepy. And what about bathroom breaks? I think there should always be 2 working if there is a tower. It may be more expensive, but safety first.
An alarm system would probably work as well.
Yeah, I don’t know know the situation, but it seems that one person, at night, etc, it seems like you are going to have people nod off, I don’t care who they are. I have had occasions where one second I’m awake doing something and the next I realize I have nodded off. It happens. If there are 2 there it’s just less likely.
And sheesh, the whole reason we have them is safety. Perhaps we can cut somewhere else.
