You work hard at work in hopes of getting promoted to a higher paying and more respected position. If you are promoted at work, the first thing you want to do is thank your supervisor graciously for giving you the amazing opportunity. Thank them and let them know that you will not let them down for giving you the opportunity. If your coworkers are congratulating you for your promotion, don’t boast about it obnoxiously. Show that you are humble by thanking everyone respectfully so that everyone can believe you deserve the promotion you got.
