Answer:
taking initiative
Step-by-step explanation:
When a leader takes an initiative, this means that he/she knows what to do in a situation or when a situation calls for her attention. She does this by grabbing the opportunity to spot on things that need to be changed in order to provide an overall progress for the entire group.
In the situation above, Mindy knew that hazardous waste is dangerous if not disposed properly. Noticing that many of the new staff improperly disposed them made her act immediately. She knew she needed to tell them, so they could changed their behavior. This is an important quality of a leader. This sets a good example for the subordinates to follow.
