I think part of the trouble is that on the SH award, living hand-to-mouth as they sometimes do, they got used to finishing a trip they may have picked up and said.. "well.. I earned X dollars from that trip."
However, others would have a trip taken off them and have the reverse sentiments.
Perhaps under the LH award they should look at the line itself and think, "Well no matter what happens, I'll be paid at least X dollars for that line plus whatever training, open time etc I can pick up."
It's all in the way you look at it.
For the line drivers, the pay is very similiar. In fact one reknown A list hour hog was heard in a bar recently comparing what he earned between the two systems, then comparing his work rate under the two, and stating he was more than happy to get his life back under the LH award.
