Workers who grit roads in west Wales have voted to strike.
Over 75 percent of GMB union members working for Carmarthenshire council highways department backed action.
Unison members also voted Yes and Unite members are expected to support strikes too.
There has been a long-running dispute between unions and the council over rates of pay for staff carrying out winter gritting duties.
Over 80 workers could strike if all three unions back industrial action.
The GMB said strikes could mean “a blanket ban on winter gritting duties” causing roads across south Wales to “grind to a halt”.
The union said Carmarthenshire had “some of the worst terms and conditions” for gritting staff.
About 70 health visitors in Lincolnshire are continuing their near month-long strike in a continuing dispute over pay and standards.
The strike by members of the Unite union began on18 November and is set to continue until 13 December.
The union said workers were significantly worse off since being transferred from the NHS in 2017.
According to the union, some workers stood to lose £150,000 over the duration of their careers due to a two-tier grading system introduced by the Tory-led authority.
This, it said, discriminated against some staff by placing them in the lower pay band and limiting their chances of progression, despite them having the same qualifications as those in the higher tier.
Steve Syson, regional officer for the union, said workers stuck in the lower tier would be £4,000 worse off a year.
