Internal hires have slowly watched their compensation erode as they transition to a line holder. I was in one of the group's who did not get credit for vacation longevity as a pro. The groups that went to the line before me started as a new hire with accrued vacation longevity from date of hire with the company. That benefit was traded away for something in the contract negotiations. At least I got to keep my three years as a pro for retirement multipliers. The guys transitioning now start at zero but they do get to keep their DC plan.
