Answer:The manager has high goal commitment
Step-by-step explanation:
Goal commitment:
This is when someone set the goal and commit to it to whatever extent that will take him to because they are personal invested in it. This means one will give their all energy and focus in setting the steps to be followed and challenging themselves towards making sure this goal is achieved.
Putting extra hours and taking short breaks is a sign of how this manager is committed to his goal. He is even challenging himself to take on unpopular decisions.
