Hopefully my suggestion re: Fedex isn't cringy.
I like this sweet talk about employers and well being. I agree with it, and after all they are writing our checks. But lets not pretend that there aren't guys out there who sit there and keep track of their rolling 12 month sick callout calendar and take convenient sickations. Or guys who commute and get hosed due to weather, mx, etc, call in honest, lose their pay, get an earful, and then learn their lesson that if it happens next time: call out sick. For some, sick time is a game played in the rolling 12 month calendar. For others, sick time is a backup to a missed commute. And yes, sick time is also used for sick time itself.
Didn't Delta guys take a huge stand in regards to their failed TA about having to get doc notes for sick calls? No pilot wants to get a doctor note. But lets be honest, there are many times when a sick call isn't really a sick call.
