Only two classes are needed,Linehaul and City..Some may say Hub is like linehaul..In a sense,it is..But..In the old days,I haven't done it lately and it might have changed,when linehaul had to clock in and help at a Hub terminal,we got paid $2 more per hour than Hub..Hub, as it stands,gets the same pay as a city driver that works the dock..So you might say,we are not the same..Personally,I don't think we should be different..Hub drivers drive the same miles we do,on some runs..So why should they be in a different class,just because they have to work the dock..Now they have managed to create another class of driver,Utility..The more classes you add,the more watered-down the job requirements get..The payroll clerks must dread payroll day..They must all wear wigs,cause none of them should have any hair left..JMO
