Juan just hired his friend, warren, to manage a team of union welders in an automotive factory. juan worked with warren before in a small, privately-owned welding shop. in the welding shop, warren was the first shift superintendent, where he modestly demonstrated that he knew more about welding than anyone in the region, and he always came up with brilliant solutions. warren knew his ideas were good, he owned up to his mistakes when he made them, and his workers successfully followed his lead, making him the most productive leader the welding shop had ever employed. however, only a month after hiring his friend, juan is disappointed to learn that warren is failing as a manager in the automotive factory. warren does his job the same way he always has, but he keeps failing to follow the complex bureaucratic procedures in the factory, he repeatedly breaks the agreement between management and the union, and his workers do not listen to him.
which of the following is most likely causing these issues?

a) warren does not possess the traits of a good leader.
b) warren's ability to lead depends upon the situation.
c) warren does not know how to behave like a leader.
d) warren's employees know more about welding than warren does.
