I’d like you to do my job. I work weekends and midnight until 0800 full time.  Yes, I get paid at a higher rate than the 9-5’ers, and I have been doing it for years. No one in my department wants my hours due to the lack of sleep you as the phone rings, door bells go, building going around etc etc. including, the unsociable hours and it is also very hard on your body. There have been studies that people who work these hours is more likely to get sick.   If it wasn’t for us shift workers, the world would come to a halt.  So when you are in dire need to go to a hospital, you will be thanking the shift workers, Dr’s, nurses, scientists, cleaners, cooks, paramedics, reception staff who attend to your needs and saving your life.  I know for a fact if there were no shift penalties, I wouldn’t be working the hours I do, and I doubt anyone would do the same, unless you’re putting up you hand to work these crazy hours for the same pay as 9-5’ers!    You wouldn’t last 5 minutes.
