If we look at the rest of the document, we see that Sharon describes her style of leadership in the following way:
“I’m pretty focused on getting the work around here done, and making sure that all the employees do what is best for the animals. I give my staff specific instructions on what to do every day, and then I check to be sure that they’ve followed those instructions exactly. I don’t tolerate mistakes.”
Therefore, based on this, we can see that Sharon's leadership style and the situation she faces do not match. Sharon does not seem to recognize that her team has been on the job for a while, and that this gives the team expertise. Therefore, she does not need to give her staff such specific instructions. Moreover, the team is cohesive, so Sharon should be focusing on developing relationship with the people on her team and taking advantage of such unity.
