Around 100 postal workers at a delivery office in south Bristol struck on 17 December for a second time.
The CWU union says its members struck because they are being asked to do more work with fewer people. Delivery rounds have been revised, forcing too much work on the staff, the union added.
Bristol CWU area official David Wilshire said there would be a meeting outside the depot on 8 January to decide the next steps.
Workers who maintain Royal Mail offices called off a planned strike in the run-up to Christmas.
Up to 1,900 engineers and cleaners employed by Romec, which maintains Royal Mail sorting offices and depots, were due to strike over the holidays. But the CWU union announced it had secured an improved deal.
Staff had been offered a pay rise of just 1.5 percent over 27 months, while bosses paid themselves bonuses of up to 15 percent. A revised offer of 3.1?percent over 15 months will now be put to members.
Lawyers in Scotland took another day of action in their fight against cuts to legal aid last month. Lawyers and solicitors at the custody court in Glasgow struck against the plans on Monday 17 December.
This follows a number of surprise strikes by lawyers and solicitors at courts across Scotland. They aren’t announcing dates in advance to maximise disruption.
The cuts they are fighting would force people with a disposable income of more than £68 a week to contribute towards their legal costs. The cuts are being implemented by the Scottish National Party government.
Bus drivers on the Isle of Man struck for three days over the holidays against pay cuts of up to £3,000.
The drivers work for the island firm Bus Vannin, formerly Isle of Man Transport. They are members of the Unite union.
Eric Holmes, the union’s regional officer, said, “This is the largest scale industrial action on the island for more than 20 years.” More than 90 percent of the drivers voted in favour of the strike.
