>> I smile and ask them if they'd like to switch with me
I worked at one place where upper management made the Supervisors' jobs REALLY stressful. When they had to replace one, there were NO volunteers and several people said they would quit before becoming a supervisor.
When we complained too much about anything to our Supervisor (the poor guy who finally volunteered), he would ask us if we would rather have HIS job. It shut us up RIGHT away!
By the way, he wound up in the hospital with something like a stress-related ulcer. It sounds like you have things well under control.
Besides everything else, you home-school your clan? I would have thought that was ALSO a full-time job.
