Their asking you about sick calls is questionable at best. Sure they make you sign a waiver but legally it is questionable. The majority of pilots are professional and honest when it comes to that. Sometimes you just get sick a lot in one year. Unfortunately there are a few Dbags out there who abuse the system and ruin it for everyone else ( i.e waiting until the moment an occurance comes off the record than immediately calling in sick again). These are the same dbags that never have any available sick time when they are really sick so they get everyone else sick because they are selfish pricks. IMO they shouldn't be allowed to ask about it at all.
