I find Desdihold's story a bit hard to swallow.
Upper management? Who is that?
If it was the FDM, the guy was on reserve and made a song and dance about a change, then bad luck! Go fly or go sick.
If it was fleet (doubt it) calling and told him to work day off, hang up. There will be no issue as it wouldn't happen.
But both of these are not "upper management".
