This. Get to where you want to be...call out sick. Call in well...go back to work. Simple...they can't control where you can go on your off days. They can't control when you get sick or why. I had one instance in my 50+ days of sick occurrences over 7 years where a note was ever requested. I asked them to foot the bill, as I couldnt afford it (early days with low FO pay) They rescinded their request.
