If your intention is to have a motivated and customer focused superstar team, then be careful what is lying around in the staff rest rooms or canteens.
The typical newspaper and popular magazine will be filled with negative gossip type content and encourage feelings of envy, scorn and other judgemental feelings in the reader. These are the opposite of the kind of mindset you would be needing in a team of caring service providers.
Ban the trashy gossip from your workplace, it may be censorship of a kind, I say so what- get over it. If you dont, then your training efforts are going to waste.
