It is vital to have a tight network of trusted peers as, at times, it plays a key role in establishing your relationship with your boss and impacting your direct reports. But since this may not be a necessity, many people tend to overlook this powerful career elixir. Trust matters even more with your peers because no one’s “officially watching", so as to say.
There's no "official" accountability levers. It's easy to put them last on your trust-building priority list. Unfortunately, though, this attitude may hamper your career graph. The truth is, I was a slow learner in this regard. Your peers aren't evaluating you on an employee engagement survey, or writing your performance appraisal. Often they have competing agendas, and of course you know it's you against them in the stack rank.
So many of us buckle down, approach our peers with cautious pleasantries, and watch our backs. But the fact of the matter is that real trust develops when no one is watching...when you've got something to lose, and yet choose to be vulnerable.
