I think it is uncanny how Perry Noble clearly identifies the 4 types of staff people. Here’s a clip, very much worth the read over at his place:

#2 – The “Can Do” Staff Member
The one thing that has to be addressed on a staff is competency level. Because, while you may have someone who loves what they do…they just might not be able to do it. (And…in my opinion, the church should hold a higher standard here than the business community; after all, there is a lot more at stake.)
Can the person doing the job do the job? OR…has their skill set and ability been maxed out? It’s a tough call…but one that must be made in order to protect the church and the staff member.
AND…let me say that the first option should always be to move the staff member to another job…because if they are a “Love To Do” staff member then they will thrive!

#3 – The “Should Do” Staff Member
This is the person on staff that gets to the office 3 minutes late and leaves 5 minutes early. They are gone a really long time for lunch…but no one ever really knows why. They spend a lot of time on their facebook pages (that are completely not ministry related) and often talk to their friends and waste time.
Sure, they get their job done–barely…but their hearts are not into it. They do what they “should do,” nothing more, nothing less!
AND they have to go! You can’t afford this kind of dead weight in your church! God’s kingdom is WAY too important to keep these kind of people around. They are not doing what they are doing because of passion but rather a paycheck. NOT GOOD!
