In every company there is a need for a Trouble Shooter just as there is a need for a repair mechanic. If you send a guy out that has done service all his career and tell him to "put that cylinder in" he's not going to have a clue how to do it. Just as if you ask a repair mechanic to figure out a complex group dispatcher problem. No Clue...

Let's not be naive about how this industry works. When I call the Union for a Trouble Shooter they just laugh and say Good Luck!!!!
