Ping! An email arrives from a colleague, asking you a question - and you notice he's also cc-ed his message to the boss.
Thoughts that spring to mind are perhaps a colleague is trying to cover their back - or possibly even catch you out?
If you brush this off as paranoia, then think again. Copying in the boss can definitely have a negative impact in the workplace, according to David De Cremer, a Management Studies professor at Judge Business School, University of Cambridge.
Professor De Cremer and his collaborators conducted six studies to see how cc'ing affects trust in the workplace, according to Daily Mail.
In one, 594 workers were asked to imagine that their co-worker always, sometimes, or almost never copied in the supervisor in when emailing them.
