Envy at work is a common experience, and how we respond to it shapes our behavior toward colleagues. This discussion explores why pushing envy down is counterproductive, what information negative emotions such as fear, anger, and envy provide, and how envy can shift into malicious behavior like undermining others or gossiping. It also covers a practical pause-and-reflect approach for using envy as useful information instead.

■ Why envy is worth paying attention to
- The mistake of ignoring or suppressing envy and treating it as mere negativity
- How different emotions, including fear and anger, signal important information
