Iwire,

It makes sense that the Jman and apprentice are charged out at the same rates, if they use jman labour hours to determine how long the job will take.

If a jman can do the project in 4 hours because of experience, the apprentice will probably take more. The relationship between the apprentice's experience and the time it takes for him/her to do the job should be fairly proportionate to the hourly rate of the jman.
