Strike action by workers is set to continue at the Sellafield site this week.
Staff employed by subcontractors at the West Cumbrian nuclear site are due to resume industrial action from Tuesday January 6.
Members of the Unite union began industrial action in September.
They are demanding site-specific allowances, which they claim are paid at other nuclear sites, from their companies.
The industrial action is covered by conditions from Cumbria police under the Public Order Act.
Marches must not start before 7am and conclude by 10am.
Any marches from Calder Bridge to North Gate must start after the turn-off to Sella Park Hotel so that their business access can be maintained.
Previously, marches had been taking up to six hours as striking workers walked really slowly – dubbed the Sellafield shuffle.
The union has also confirmed to police that another week of action is planned from next Monday, January 12.
There was no industrial action from December 22 to January 2.
Sellafield Ltd is not involved in the dispute.
Previously, a spokesman told Cumbria Crack: “The industrial action taking place at Sellafield is the result of a pay dispute between some Unite union members and their employers.
“As the people involved are not employed by Sellafield Ltd this is not a dispute that we can resolve.
“Our priority, as always, is to maintain the safety and security of the Sellafield site.
“We have provided guidance to our employees who may be impacted in travelling to the site during the action.
“We will also continue to support Cumbria police as they work to minimise the impact of the action on the local road network.”
