Over 500 taxi drivers in Dundee struck last weekend as part of their long-running dispute with Dundee council.
Union officials have also called more industrial action during the Christmas period if the council refuses to have a “sensible discussion”.
Graeme Stephen, chair of the Dundee Taxi Association, said, “I expected around 350 to strike. When we realised how few taxis were working, we were delighted.”
Drivers’ grievances include a lack of taxi rank spaces, the large number of licence plates issued and the high number of private hire drivers operating in the city.
“If the council still won’t move then there will be a lot more strikes and rolling road blocks,” Graeme Stephen said. “With Christmas and New Year coming up, we have a few more surprises up our sleeve.
“Unless say they have got something to offer, then we aren’t going to get anywhere.”
