he has worked for them for 5 years, been an absolutely exemplary, loyal employee. he started as a warehouseman and has been promoted 3 times since being there, and is now a senior manager. he has completely turned around his branch and its earning about 5 x the profit it was when the last manager was in charge. the last time he took time off sick was about 3 years ago (for 2 days) when he had swine flu.
he has gone in to work on loads of occasions when he has felt unwell, because they DON'T PAY SICK PAY. basically, they just ASSUME people are skiving.
so anyway, he is really poorly with flu. yet he has dragged himself in today, so he is going to infect his whole team, customers and probably not be able to even do his job properly just for the sake of "presenteeism"
and who does he work for, I hear you ask? well, its not just a small back street business who probably genuinely can't afford to pay when workers are absent - this is a huge, multi, multi million organisation....
YOU TIGHT, STINGY, HORRIBLE BASTARDS, YOU SHOULD BE ASHAMED OF YOURSELVES.
