“No, I don’t have the time”
When your boss asks you to do something (as long as it doesn’t violate company policy, of course), there is no reason for you to ever answer with the word “no”. Even if you are super busy with other projects and you really feel that you don’t have adequate time to do it all, ask your boss to help you prioritize which task you should do first. That way you don’t look like an employee that has a “can’t-do attitude,” but rather, one with a “can-do attitude.”
“It wasn’t my fault: It’s so-and-so’s fault.”
Playing the blame game is a treacherous road to go down, and it’s childish. If you are innocent, then explain to your boss why. You should never throw any of your coworkers under the bus, especially if you may be at fault. If your boss sees that you’re frequently pointing the finger, at some point they may wonder who really is to blame. Check out these 16 smart ways to get your boss to trust you.
