If they are sick they should call in when they realize they are sick and not play Russian roulette with the company and passengers and take a chance on not being called out that late. I have flown with flight attendants who were not sick who called in sick 'just cause they could'. One flight attendant called off sick off a trip I was on because she woke up too late to take a shower at the hotel. While some may be legitimately sick, others are just sick and tired of being here. I flew international and heard the excuses for not wanting to go out at midnight when called out to replace a crew. I had so many tell me that they would just take a no-contact because it was better than having to go out that late. Tickets for international travel are expensive and the customer should not have to suffer for employees not wanting to work. When you bid the transatlantic service you know what is in store for you.
