Was 2013 a bad year for your credibility rating? If you’re honest, you might have to admit to a slip-up or two. (Maybe not on par with the most notorious celebrities and politicians, but bad enough!) Perhaps you were late more times than you would like to admit, you missed several deadlines, you told a few white lies to clients, and somehow you turned into one of the office’s top gossips. There may even have been a couple of bigger transgressions: like promising to increase your sales by 50 percent and then coming in way under the mark (tanking your department in the eyes of the higher-ups).

Is it too late to redeem yourself?

Probably not, say Julie Miller and Brian Bedford, coauthors of “Culture Without Accountability—WTF? What’s the Fix?” Chances are you haven’t hit the credibility point of no return just yet—but salvaging your image requires making a herculean effort to be more accountable in 2014.

Here, Miller and Bedford share a tip to help you repair your credibility after it has taken a hit:

Credibility Repair #4: Speak up when you see something wrong. Remember that time when one of your peers was throwing his weight around and bullying one of his employees? Not wanting to get involved in the drama, you took the “none of my business” approach to dealing with the problem. You chose not to speak up about the guy’s bad behavior to keep yourself out of the line of fire.

“Here’s a reality check,” says Bedford. “Ignoring someone else’s bad behavior is just as bad as committing the act yourself. When people see you ignoring these problems, especially when you’re in a position to do something about them, they think you’re approving the bad behavior. They assume you’re the same kind of person as the manager yelling at his employees. Don’t be guilty by association. Speak up and show that you value fairness and respect.”
