Tom Fair, a driver and salesman with the company, says they'll be striking around the clock.
Fair's usually on the road making runs to Martinsburg, West Virginia. Now he's holding signs that read "Unfair to Workers."
"We're only getting paid $60 to work on major holidays," Fair said. "You know everybody you talk to usually gets a full day's pay."
They claim workers in Johnstown, Pennsylvania are making more than them for the same job.
"Whenever I'm out there doing my best to do the job and someone else in Pennsylvania gets the same job and more benefits and more pay than me, it kind of hurts a little bit," Driver Charles Wilkins said.
The union says the company refuses to negotiate on their pension fund and back pay. They haven't had a new contract since 2011, and the last time they met at the bargaining table was June.
Fair says, "I don't know how things are going to turn out I mean hopefully it's great and we find a settlement everybody's happy but you know and sometimes it doesn't work out and I may be unemployed."
Office workers who are not in the union are now making deliveries, according to the striking workers.
WHAG reached out to Potomac Farms. They say they have no comment on the ongoing situation.
