No sir you are wrong, and that is exactly what pisses me off!! Contractually all seniority drivers must be working before any helpers. So, if the higher seniority guys stop volunteering for days off, they have to find something for the cover drivers to do, even if it is to use them as helpers,(at their regular rate of pay by the way) so you are causing the problem by taking days off.
By the way I am a 22 year employee so don't think I don't have ample opportunity to go home!!
