When my daughter was ill, prior to the op, she still went to work because if she hadn't, the nursery would have been short staffed. She worked for as long as possible, against her doctor's advice, and only went 'on the sick' once it was physically impossible for her to continue working. she actually loves her job, her colleagues and (most of) her charges.
So, spice, your snide remarks are totally unwarranted. And, if you can only see one side of the coin, there's not much point in any further discourse.
