There will be no industrial action at the Sellafield site from Monday.
Members of the Unite union began striking in September to demand site-specific allowances, which they claim are paid at other nuclear sites.
The workers taking industrial action are employed by subcontractors on the West Cumbrian site and not Sellafield Ltd, which runs it.
The union has to notify Cumbria police at least six days before planned industrial action and no notification has been given for the week commencing January 26.
Union members also did not strike from December 22 to January 2.
Cumbria Crack understands that union members will be asked to take part in a ballot soon about whether to continue with the industrial action.
However, questions we asked Unite about this and the industrial action remain unanswered.
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.”
