Jobs are a necessity in life. Although we'd rather be anywhere else besides work, it's rather important to keep a job because sometimes work can be difficult to find. Once you find a job that is suitable for you, you should do everything in your power to avoid losing it. Need some tips? Here's 17 definite ways to get fired from your job, so make an effort to avoid doing any of these!

1. Being Rude or Disrespectful.

Kill that attitude because your smart-ass comments probably aren't going to make your boss laugh. You're not going to get any brownie points being a jerk, so keep all those slightly offensive comments to yourself.

2. Being Straight-Up Inappropriate.

Sexual harassment is never acceptable.

3. Not Taking It Seriously and/or Slacking Off.

If it's obvious that you don't care about your job, good luck holding onto it. Motivated, dedicated employees are valued while slackers are given the boot.

4. Not Following Instructions.

You may just be lazy, but your boss may think you're lazy and stupid. If you are given instructions to do specific tasks and you blatantly ignore them, then what use are you to the company?

5. Not Honoring Your Commitments.

If you commit to something, you need to actually commit to it. Follow through with what you agreed to do. Do not neglect your responsibilities because that reflects poorly on you.

6. Talking Crap About Your Coworkers.

No one likes workplace drama. It's pointless. It's unnecessary. Work is stressful enough as is; you don't need to be adding to it by spreading stupid rumors.

7. ...Or Even Worse: Talking Crap About Your Boss.

What goes around, comes around, so be prepared. You may think your boss is an actual demon from hell, but keep that fun little thought to yourself.

8. "Quitting" Without Actually Quitting.

Falling off of the face of the planet does not constitute as an official resignation. Just because you stop showing up or stop submitting reports does not mean you've officially quit. If you don't want to work somewhere anymore, man-up and just say so (but say so politely). Pro tip: Giving a two-weeks notice is always appreciated.

9. Lying and/or Making Up Excuses.

Did you miss that deadline because you were deathly ill, or were you hungover from your BFFs birthday bash? One way or another, someone will find out, and the consequence will be much more severe than what it would have been before if you had simply told the truth initially.

10. Cheating/Plagiarizing.

Cutting corners is not only unethical, but it also can be illegal.

11. Constant Complaining/Having a Bad Attitude.

Yeah, work probably isn't your favorite thing to do, but nobody likes a Negative Nancy. Constant complaining makes work a drag for everyone, and guess what? If you hate it so much, go work somewhere else. No one is forcing you to be there.

12. Excessive Tardiness.

Everyone is late every once in a while, but if it becomes a constant habit then you become undependable. Dependability is a very important skill, and if you show that it's difficult for you to perform a simple task, such as showing up on time, then your future with that company does not seem promising.

13. Coming Into Work While Intoxicated.

Self-explanatory. Just don't do it.

14. Using Foul Language.

It's simply not appropriate for you to be throwing the f-bomb around in your work environment. It's definitely not appropriate to be using bad language in front of customers. This is a negative representation of your company.

15. Stealing.

Once again: unethical and also illegal.

16. Being Romantically-Involved With Your Boss.

First off, your coworkers will hate you because special treatment is unfair. Second off, you'll feel the wrath of the HR department. There are plenty of fish in the sea, so pick one who doesn't happen to be your manager.

17. Sleeping on the Job.

Again, self explanatory. Your boss isn't paying you $10 an hour to catch up on sleep.
