Workers have different attitude towards their works,How can you manage them to be a good and efficient worker?

There is a leadership style called "coaching" I feel would be very appropriate for this situation. In this case, you have people with good knowledge of their jobs but not motivated. One of the things I do is have them see the big picture, on why it is necessary for this job tasking to get done. Also, if needed, I would add value to their work; in other words, show them their work is an absolute must for mission accomplishment which can help motivate them as well.
