What is more important, working for an effective leader or an effective manager? Explain your answer. I think it is more important to work for an effective leader than for an effective manager. A person must first become an effective leader before becoming a manager. Working in a unit with an effective leader, nurses will first turn to the leader before the manager, this is how the chain of command works. This will keep things in order and hopefully a solution will be found more quickly. Also to become a manager, one must show leadership skills to reach that position. 3. Investigate whether there is a peer support program for substance abuse and/or mental illness in your state. Find out how the program is administered. What is its success rate? How the program assists nurses?
