Without actually talking, you may still be communicating with your boss and everyone else in your office. The concept of body language is nothing new. If you have problems you don't dare talk about, you may still be telling people about them anyway with your body language, according to a recent I Hate Filing newsletter from Esselte.

Here are some ways you may be sending the wrong messages and some tips for avoiding them.

Slumped shoulders. According to communication experts, this may say that you're tired and perhaps unable to keep up with the workload you've been given. Make a conscious effort to draw your shoulders back and stand up as straight as you can, which will say that you're ready to handle anything that comes your way.

Rolling eyes. This classic body language communicates sarcasm, disgust, or exasperation. But remember, you are expected to work as a team player. Because rolling our eyes is something we've done since childhood, it may be a bad habit. When your boss asks you to help meet an important deadline, your eyes rolling back as if you're annoyed will annoy the boss.

Shuffling feet. Much like slumped shoulders, this can communicate that you're tired or, maybe worse, you're unmotivated and disinterested. Maybe it's a habit, but concentrate on taking full, energetic steps in the office, which communicates you're agile, both on your feet and in your thinking.

Head down. Here's another classic that communicates you're attempting to avoid something. Is it responsibility? You wouldn't want to ever verbalize that to your boss. By keeping your head raised, you're showing you can handle challenges and you're looking forward, ready to tackle your responsibilities head-on.
