Bus drivers in Weymouth entered their third week of pay strikes this week.
They walked out on Monday and were set to again on Wednesday, Friday and Sunday.
The 110 Unite union members want bosses at First Dorset to pay them the same rate as workers in nearby Yeovil.
One worker said, “There is not an end in sight for us. All the drivers have had it for years. They have always been the poor relations.”
They are paid £8.80 an hour, compared to £9.50 an hour in Yeovil. Workers picketed First’s offices in Weymouth.
The firm is spending a “ridiculous” amount of money on bringing in scabs, said the striker.
“What they are spending at the moment on drivers coming down, that would have paid for our rise.”
