When evaluating employees, it is important to look at performance numbers AND the impact the employee is having on your team and the rest of the company.
Are they a Positive influence on your team, or the change management program you are implementing? How are they impacting the success of others on the team?
Attitude is contagious, fostering and supporting a positive attitude is just as easy as ignoring a negative one, but has a greater overall benefit to your organization.
Don’t let performance overshadow bad behavior. Identify the behavior, address it, and look to be a positive change agent in your organization.
