Saying Thank You as a positive reinforcement. A simple “Thank You” is a compassionate way to reward an action, behavior, or job well done. It is one of the most powerful forms of positive reinforcement. Saying “thank you” is gratifying. It also implies a certain behavior that occurs again to get more of the same reward. It’s reinforced. (1)

It can be easy to be critical of others, but it just might be more important to be appreciative.

Positive effects.

Saying “Thank you” has personal positive effects. It is beneficial to both you and the person you are thanking. Research shows saying your thanks – your appreciation — will make you feel better. It is good for your health, mood, and general well-being.

“If both parties are benefitting from this, I think that’s the type of action we should be pursuing more often in our everyday lives,” (2) says Amit Kumar of the University of Texas at Austin’s McCombs School of Business. You are actually doing yourself a favor each time you give someone a heartfelt thanks and you may not even know it.

Say “thank you” to your boss

Saying thanks has proven to be essential, but it sometimes can be awkward when saying it to your boss. You worry about finding the right words to use, the length, frequency and intent. Could your boss take it the wrong way?

Bringing the positive effects of appreciation and gratitude into the workplace leads to the “we’re in this together” mentality. This will help in bringing all of you together for success. (3)

Here are some tips:

  • Be sure it is absolutely true. Make sure the words you are about to say are what you absolutely believe in. There can’t be any doubt.
  • Focus on the person you are thanking, not just the act. instead of just saying thanks for this or that, for example, say something like, “Thank you, you’ve always been considerate and kind.”
  • Say it privately. Surprise your boss with a simple thank you note or a message.
