4.5 hours of your own sick pay isnt nearly worth 4 days off and getting paid for it sick or not. If I'm sick, I'm sick. 1,2,3,4 days in a row, whatever it may be, I'm not coming to work. The time off plus getting paid for it is more valuable than a measly 4.5 hours anyday.
Speaking of sick calls, what happend to their "wellness program" and good food in all the crew rooms? Vanished like a fart in the wind.
