Actions speak louder than words, especially in professional setups. If you are in the habit of rolling your eyes, constantly yawning or sitting in your office chair in the most casual way possible, then we have bad news for you. While all of this might appear insignificant, it never goes unnoticed and always creates a bad impression. Nothing spoils your image in the office as soon as this workplace habit.
How to turn it around: Constantly remind yourself that you are in a professional setup that requires you to be aware of your body language. Notice those around you and see what looks appropriate and what does not. This will help you segregate a set of habits.
