Unpaid/paid sick leave is an ongoing challenge in the work place. As an employer, who has an unpaid days off policy, we have solved the problem of "my child is sick so I can't bring them to daycare" (a phenomena that affects female workers far more than their spouses), "I am sick this morning (or still drunk from the night before)", etc by sharing the financial consequences with the worker of their absence. And yes some people "tough it out" but since many of people are commission based, therefore unpaid if not working, peer pressure works quite effectively.Now as anside with the very public presence of a person with acomprimised immune system, me, the rules are simple. Sick -- stay home out of courtesy, and if that is inadequate you are sent home immediately. Last years H1N1 has changed people's views radically. Now at the clinic-- having an infectious disease makes you unqualified to work in that environment and you should be sent home also. I like the example of a salad maker at your favorite restaraunt with Hep C -- if they take "precautions" would you eat there? Few healthcare workers volunteer for the first salad. As for the loss in salary-- switch shifts, etc. It is better then affecting the health of patients.
