Unite/NAECI industrial action at Sellafield

A second period of industrial action has been planned by the Unite union for its members covered by the National Agreement for the Engineering Construction Industry (NAECI) and the Construction Industry Joint Council agreements.

Those taking action are not employed by Sellafield Ltd.  The pay dispute is between individuals and their employers and therefore it is not for Sellafield Ltd to resolve.

The action will take place from 00:01 on Saturday 4 October 2025 and continue until 06:00 on Monday 13 October 2025.

We expect disruption when accessing the Sellafield site during the period of industrial action.

Therefore, wherever practicable and feasible, managers should enable teams to undertake their normal work from a different location, including an off-site office or from home.

This will help to protect availability of critical resources and to mitigate traffic disruption and impact on our local community.

Please car share if possible - not only when accessing site, but for travel to off-site offices which we expect will be busier than usual.

Keep up to date

You can keep up to date via our text and email service providing messages from the safety and site shift manager. Sign up for Sellafield site updates here.

Strike details:

  • The strike action is due to begin at 00:01 on Saturday 4 October 2025 and continue until 06:00 on Monday 13 October 2025.
  • We are waiting for confirmation, but we should expect picketing at all Sellafield site gates.
  • The action affects the Sellafield site only – not off-site offices in Cumbria or Risley.

Information on travel/transport/site access:

  • We may change gate opening times to help traffic flows. We’ll update the electronic road signs with any changes.
  • Cumbria Police will manage traffic disruption from the A595 and Yottenfews car park. We will share detail about this when we have it.
  • Where we need to make changes to our park and rides and Risley bus services, we will update this communication.
  • Pedestrian turnstiles will remain operational at all site gates (access code needed).
  • There may be some delays to on-site deliveries.
  • Road safety: Drivers, pedestrians, cyclists and motorcyclists all need to be extra vigilant and careful as ‘normal’ traffic flows could change. Wearing hi-vis is more important than ever.  Drivers have the right to proceed safely past pickets without engaging with them.
  • Normal Sellafield site access arrangements will apply – you will require a valid SOVA to access the Sellafield site.
  • To support site access during this week’s period of industrial action, the current YOVA restrictions for Yottenfews car park have been temporarily suspended. Colleagues are encouraged to make use of the Yottenfews where possible, as this will assist in reducing local traffic congestion and improving journey times onto site.
  • Some B111 training courses have changed location – the attendees of those courses have been contacted directly.

Expectations on attendance:

  • Our workplaces will remain open and normal working patterns should continue.
  • We expect traffic disruption to the Sellafield site. Therefore, wherever practicable and feasible, managers should enable teams to undertake their normal work from a different location. This may be an off-site office or from home.
  • If you use an off-site office as an alternative location to site, please use the ‘hubs’ for the area of the business you support.
  • If you work from home on strike days, you line manager must be able to contact you. You must also make yourself available to return to their normal work location, if required.
  • Line managers may request employees to alter start times, in line with their contractual obligations, to meet specific operational requirements.
  • It is particularly important that we all follow our procedures on absence management. See intranet for guidance.

General guidance:

  • As always, the safety and security of the Sellafield site, our workforce, and the local community remain our priority throughout the action.
  • Whilst we try to put in place contingency arrangements in the areas most impacted by the strike action, we respectfully remind everyone that it’s our personal responsibility to ensure our working environment remains safe, hazard-free and fit-for-purpose.
  • Please be respectful to colleagues, regardless of their employer, throughout this period of disruption.
