Things like playing games on the cell phone while descending in Metric RVSM airspace as pilot flying seem to be considered a workplace entitlement with some of my colleagues. If I show more than mild displeasure, my coworkers will clam up and respond tersely for the rest of the trip.
Man alive that is bad. My copilots will ask me if it is ok to send a text when we are on the ground and the after shut down checklist is complete. Answer " sure thing, thanks for asking" .
