That was a sign, printed on dot matrix printer paper, which hung in the breakroom of the McDonald’s where I worked. While that was nearly thirty years ago, I suspect that same sign is still there (though probably reprinted on a laser printer). But the idea behind it has changed. Your mother may not work at McDonalds, but the company—and others that hire low-skilled employees—are increasingly taking on the role of in loco parentis.
Lessons in basic life skills that were once taught by parents—such as punctuality, self-direction, basic personal hygiene—are increasingly being provided by the shift manager at the local fast food restaurant. That is why it’s absurd to claim that companies that are willing to hire people who are unqualified for the labor force are somehow getting over on the American taxpayer.
