Today is National Boss Day, probably an uncomfortable day in which employees feel mandatory to give some appreciation to their boss, even though they think it isn't worth it.

Nevertheless, according to a uncountable studies collected by Business Insider, there is a better way to start with the right foot and impress him or her instead of giving him a cheap coffee mug:

-Try to wear red. According to a study published in the Journal of Hospitality and Tourism Research in 2012, red makes others view you as a very focused, committed and trustworthy employee.

-Sleep early. No one wants an employee with an awful performance. A study published by the University of Toronto points out that people who wake up early are typically happier, healthier, have a better performance in their daily tasks, reach a greater career success and are highly satisfied with their lives.

-Wear makeup. Women who wear makeup are considered as more competent and likeable than those who don't, according to a study conducted by Procter & Gamble.

-Act like a leader. In order to get promoted, every employee needs to show leaders skills, decisiveness, calmness under pressure. According to a study published by the Center for Talent Innovation, this "executive presence" counts for 26% of what it takes to get promoted.

-Communicate virtually. It seems that the more powerful a person is, the less one can arrange personal meetings with him or her. Bosses are managing lots of things during the day and what they don't need is to feel they are losing time. According to a study of the Imperial College of London, an employee will have a better chance to have a healthier relationship with the boss (actually, even better chance to get a satisfactory answer to a request) if it is done by a virtual medium.

-Smile. Smiling makes your body feel good and helps you to overcome your job's bad side, according to Dr. Carol Kinsey, author of books like "The Silent Language of Leaders: How Body Language Can Help - or Hurt - How You Lead."

-Try to keep on your own business. People who helped others performed worse than those who asked for help, said a study published in the 2012 Applied Psychology Review. Avoid interruptions, they just keep employees out of focus and prevent them from finishing their work.
