The only way that the top line haul drivers will be effected would be if they were to make all of the high mileage runs 4 day bids, much like has been done in the city. Changing to a 4 day bid would keep a lot of guys working and be good for the company.
This has been forced into the city bids for quite some time. Every city driver from top to bottom has taken a hit. For any Big time road driver to think they don't have to because of seniority, that's just self centered, and foolish to think it will continue forever.
Remember too that the pay differential for road (line haul) was based on running at night and back when most every run was a laydown. It's hard to justify the difference between a #1 city and a #1 road on a daytime turn running 630/day.
As for earning your spot and screw everyone else... Well that's only part of the equation. A lot is just the luck of the draw. There are guys with 25 years line-haul that still don't have the kind of run that some 5-10 year guys have.
I'm all for making the most you can, but when every job class takes a hit, don't be surprised when the purple spotlight shines on you too.
