We send people with a GED and no specific skills to work for $15/hour. Two or three hours in, they leave without notifying anyone. Why? Maybe “It’s not for me.” or, “He disrespected me”, but at least the girlfriend works.
That's inevitable when the individual quickly realizes they're in over their head.
I'm seeing folks in positions well beyond their capabilities and many are either folding in place by leaving stuff undone or disappearing as quickly as they can. It's worse now because staffing is so thin that those over their head can't hide in a group. The trend is for roughly a half-experience hire, meaning that the person filling the position has about half the experience of the person who vacated the position, not at the time the departed left but at the time the departed was hired into the position originally.
The responsibilities of those who fold in place fall onto others around them, increasing their workload and influencing their departure as well. I've witnessed paired departures where one had told the other, "if you go, I go, because I don't want to get stuck with all that's going to roll downhill."
I think the level of addiction is much higher than we realize. May not be just drugs, but also gaming and porn. They can’t bear to leave their “safe space” for more than a few hours before they are jonesing to get back into their alternate reality.
