If you're like most people, you're worried about becoming the next casualty at work. Times are tough indeed. And if your company is like most other companies, you've witnessed at least one round of layoffs since the economy crashed. It's easy to get down in a crisis like this, but here are some tips to help you keep your job.

1. Don't be a whiner. If you're still gainfully employed, you should consider yourself lucky. Don't whine about how much work you have or how many nights you've had to work late. Nobody likes a whiner. And if you are one, you'll be an easy target the next time the axe has to drop.

2. Do have a positive attitude. A good attitude goes a very long way. Just keep reminding yourself how lucky you are to have a job, and the rest should come easy.

3. Don't be a nine to fiver. Now is not the time to be a clock watcher. You've got to prove how dedicated you are to your job and your employer.

4. Do come in early, and stay late. Working longer hours shows you care about your job and the company.

5. Don't hide behind your desk. Not being visible isn't going to help you keep your job. In fact, it's the opposite. If nobody knows who you are or what you're doing, there may not be a good reason to keep you.

6. Do get noticed. Volunteer to take on new projects, show your willingness to take on additional responsibilities, and be productive. And make an effort to interact with people at senior levels.

7. Don't  gossip. Anything you say can and will come back to haunt you.

8. Do stay focused. Be proactive and set goals for yourself. And remember to let your manager know when you've accomplished them.

9. Don't limit yourself. It's easy to become complacent, but if anyone can do your job, your job will be at risk.

10. Do branch out. Learn as much as you can about the business you're in. Nobody is indispensable, but you can come pretty close if you can take on responsibilities that go beyond your job description.

Following these tips won't guarantee that you'll keep your job, but if don't follow them, you're pretty much guaranteed to lose your job.
