I have to throw the flag on this one. I'd like a few legitimate reasons to block a calendar please. The only people you are blocking from seeing your work schedule are those people (pilots) that access your "calendar" through VIPS. Only other pilots use VIPS. Selecting block calendar in VIPS does not affect anyone other then us pilots. I'm slightly open to listening to why a pilot would have a legit reason to hide his work schedule for other workers. The obvious reason of I don't want others to know; how much/little I am working, which disputed pairings I'm on, how I'm dropping trips for union then flying draft, how my buddy the scheduler is sliding me draft under the table, etc......I see lots of reasons to hide, but none I'd call legit.
