Also, the reason it seems freight gets such a huge increase at the end of the progression is because in the new contract we don't get any cost of living raises at anytime during the progression. We get all yearly increases with the very last step of the progression, if that makes since. However, once you finish the progression you will then receive the yearly wage increase each year.
The reason freight pays so low the first three years and it changed to a 4 year progression is because no one cares,it didn't affect the people that voted on it.They got theirs.
