• If you routinely stay 30 minutes after your shift doing free work, you’ve given away 72 hours per year. Now you’ve just traded away a long weekend that you could have spent fishing, skiing, traveling, or doing literally anything else that you want.
  • Sixty minutes after each shift? That’s the same time commitment as working 16 additional shifts every year. You’re working one month each year for free. No bonus. No thank-yous. No recognition. Just more work.
  • Ninety minutes after each shift? That’s nine full days of your life every year. Not theoretical days. Real full days. Go take a trip to Europe instead. Or stay home and do nothing. I bet you can find something better to do with that time than volunteering at the hospital.
