It's a dog-eat-dog world and unfortunately, if you're not single, skinny and good-looking, you're more likely to be scraping the bottom of the barrel.

At least that's true in the corporate world, where serious advantages exist if you happen to be a the right gender or have an optimal marital status.

Recent reports show single American workers, for example, have faired far better than married people through the recession: 90 percent of reported job losses by singles have been recovered, according to CNN.

But singles aren't the only people coming out on top. That poor intern making coffee runs all day and that coworker who seems to sleep at the office may in fact be cashing in on those inconveniences and in turn cutting you in the promotion line.

Here are the 10 types of people that are coming out ahead of you at work, and some tips to help you be more like them:

  • The Early Bird

    Getting a crack at things early in the morning not only <a href="http://www.jobacle.com/blog/2008/2/26/the-early-bird-gets-promoted.html" target="_hplink">shows your dedication</a>, but can also help keep you on track for more <a href="http://www.salon.com/2012/03/14/bring_back_the_40_hour_work_week/" target="_hplink">traditional working hours</a>.

  • The Night Owl

    While the early bird may get the worm, the night owl <a href="http://gothamist.com/2012/03/06/white_collar_worker_game_seamless.php" target="_hplink">gets free dinner</a>, reports Gothamist. While <a href="http://www.deseretnews.com/article/865554913/Is-leaving-work-late-the-new-on-time.html?pg=all" target="_hplink">more workers are burning the midnight oil</a>, they're also snagging meals on the cheap thanks to food stipends granted by companies.

  • The Baker

    Everyone loves free cookies. Even if you end up <a href="http://www.forbes.com/sites/meghancasserly/2012/02/16/playing-house-in-the-office-the-cookie-conundrum/2/" target="_hplink">more known for your baked goods</a> than your sales reports, no one wants to fire the in-house Betty Crocker.

  • The Hottie

    It pays to be beautiful. "Attractive people are judged more favorably, treated better, and cut more slack," <a href="http://www.psychologicalscience.org/index.php/publications/observer/2011/april-11/beauty-is-in-the-mind-of-the-beholder.html" target="_hplink">according to the Association for Psychological Science</a>.

  • The Coffee Runner

    Do you ever feel a twinge of guilt for the intern stuck taking 12 different coffee orders? Don't. Her latte <a href="http://www.starbucks.com/promo/runner-reward" target="_hplink">is on the house</a>.

  • The Flirt

    A little flattery can go a long way. Some innocent flirting can help you win small battles or big ones, for example, <a href="http://www.learnvest.com/2012/08/want-to-succeed-in-your-next-negotiation-be-a-flirt/" target="_hplink">dominating a salary negotiation</a>.

  • The Health Nut

    It also pays to be healthy. Some employers even offer better health insurance premiums and <a href="http://articles.nydailynews.com/2010-01-26/entertainment/29436953_1_discounts-free-health-screenings-chelsea-store" target="_hplink">deeper employee discounts</a> if you pass a few health screenings.

  • The Man

    If you're a dude, your boss <a href="http://www.cbsnews.com/8301-505125_162-57476557/why-men-get-bigger-pay-hikes-than-women-do/" target="_hplink">assumes you're a good negotiator</a>, and is more likely to give you a bigger promotion to avoid the conversation altogether. Women, on the other hand, are <a href="http://www.guardian.co.uk/lifeandstyle/2010/aug/27/women-wont-ask-pay-rises" target="_hplink">less likely to argue over pay</a>, so they often get stuck settling for the first offer.

  • The Ivy League Grad

    While no one likes a bragger, a little shameless self-promotion is a good way to get yourself on the boss's radar, especially if you've got a <a href="http://www.huffingtonpost.com/2011/04/08/college-return-on-investment_n_846533.html#s262350&title=California_Institute_of" target="_hplink">pricey degree to back it up</a>.

  • The Singleton

    The economic recovery has been more kind to single people. Five million unmarried Americans lost jobs during the recession, but nearly <a href="http://money.cnn.com/2012/08/15/news/economy/jobs-single-workers/index.html" target="_hplink">90 percent of those jobs have been recouped</a>, compared to only 22 percent of lost jobs for married workers.
