I seem to remember that they tried this once before . So everyone simply went to the doctor to get a sick note . Most people who would have simply taken a few days off on self determination Then decided that if they had to be inconvenienced enough to see a doctor they might as well make it worthwhile
Well it lasted about 2 months , the medical bills went through the roof and pilots ended up taking more time off than they would have had they been considered adult enough to make a personal decision
Let's see how well it works this time
