If you’re running a workplace, then it’s in your best interests to ensure that everyone is happy, fulfilled, and satisfied in their work. If they are, then not only will there be a more pleasant atmosphere in the workplace, but you’ll find that work productivity and output is much better than if there is a hostile environment.
You might not think that there is any time for rest and recuperation, but it's important that we all have a bit of downtime. Being a parent is a full-time job, and if we spend a lot of effort teaching our children the various skills they need to get ahead in life this leaves us feeling burnt out. This is doubly true if we are teaching our children skills that we don't necessarily know ourselves, so we are learning them as well.
