I once earned a week of vacation time in a month when we were installing a new time system.

YOU are on duty 24/7/365 whether you like it or not. Your hours are not counted, your worries are your own, a single weather “incident” can ruin a season or even the business.

Our company moved to a new location over the Thanksgiving weekend and they wanted my lab up and running by Monday so I worked long hours to get it done. They even brought in Thanksgiving meals for us. I succeeded in getting the lab up and running and received a hefty bonus from the CEO.
