I recall a lengthy "Cat and Dog" from a former ACP named Jim Rxxx that (at great length) explained that a pilot could use sick time when a child or spouse was sick. Then along comes an ACP named Don Mxxxxxxxx that changed all that with one email that said a pilot could only use sick time if the pilot was physically sick - period. If it is not in writing and signed by the company it is subject to change at the whim of the newest management team.
