- Over 100 ABM workers voted 97% in favor of a strike at London Stansted Airport.
- The walkout targets passenger assistance services for travelers with reduced mobility from April 17-20, 2026.
- Airlines like Ryanair and easyJet face potential departure delays due to slower boarding processes.
(LONDON STANSTED AIRPORT) — More than 100 ABM passenger assistance workers at Stansted Airport voted 97% in favor of a strike from Friday, April 17 to Monday, April 20, 2026, a walkout that Unite the Union said could disrupt assistance for passengers with reduced mobility and slow flight departures.
Unite the Union organized the action in a pay dispute involving ABM staff who provide the airport’s PRM service, the assistance system used by passengers with disabilities and reduced mobility before aircraft doors close.
Airlines operating heavily at London Stansted, including Ryanair, easyJet and Wizz Air, face the prospect of delays if boarding takes longer and departures miss their allocated slots in the airport’s tightly managed airspace.
The workers at the center of the dispute handle assistance that remains legally protected during industrial action. UK law requires PRM support to continue during labor disputes, which means the service cannot simply stop even if staffing levels fall.
That legal duty shifts the pressure onto operations. Passengers who have pre-booked PRM assistance face the highest risk of disruption because the service must still be provided, and any shortfall in staffing can slow the process of getting those passengers to gates and onto aircraft.
At an airport such as Stansted, where low-cost carriers rely on fast turnarounds and tightly timed departures, longer boarding times can spread quickly across the schedule. A delay in closing aircraft doors can lead to a missed departure slot, and a missed slot can push an aircraft further back in the queue.
ABM confirmed it had received notice of the walkout and said it had been in talks with the union. “ABM has received notice that team members at Stansted Airport working on passenger assistance will go on strike. We are disappointed that industrial action is to be taken given our constructive engagement with Unite the Union.”
Unite warned that the industrial action will lead to delays caused by PRM staffing shortfalls. The union’s position places the dispute squarely on pay while also highlighting the pressure that reduced staffing can put on airport operations.
The action affects a part of airport work that many passengers never see until it goes wrong. PRM service workers assist travelers with disabilities and reduced mobility through critical points in the airport journey, including the period before boarding is completed and aircraft doors close.
Because the dispute involves workers tied directly to boarding, the disruption risk extends beyond the passengers using the service. Aircraft waiting to complete boarding can hold up stand use, departure sequencing and airline schedules, particularly for carriers with dense short-haul operations.
Ryanair, easyJet and Wizz Air are among the airlines named as potentially affected by the strike. All three carriers depend heavily on efficient ground handling and on-time departures at Stansted, where even short delays can carry into later flights.
The voting result, at 97% in favor, pointed to strong support for the action among the workers involved. With more than 100 ABM passenger assistance staff set to strike, even a limited reduction in available teams could place strain on a service that the law says must continue.
Passengers who have already arranged PRM support are likely to watch the strike especially closely. Pre-booked assistance gives airports and contractors notice of what is needed, but it also means any staffing gaps are immediately operational rather than theoretical.
Stansted Airport’s role as a busy base for budget airlines adds another layer of exposure. The airport’s tightly managed airspace leaves little room for slippage once flights begin missing planned departure times.
ABM’s statement signaled frustration with the decision to strike while also stressing that engagement with Unite had been under way. The company did not set out any broader public response beyond saying it was disappointed by the notice.
Unite, by contrast, framed the dispute around the immediate practical effect of staffing shortages in the PRM service. Its warning on delays suggests the union expects the operational consequences to be visible quickly if the strike proceeds on the announced dates.
Travelers passing through Stansted during the planned walkout period will need to monitor flight status and check directly with their airlines for updates. Anyone using the PRM service, or traveling with someone who does, should stay alert to any changes in assistance availability and consider alternative travel plans if those options are available.
The strike notice covers a narrow but essential airport function. If the action goes ahead from Friday, April 17 to Monday, April 20, 2026, the pressure point at Stansted will not be check-in desks or security lanes, but the final stretch before boarding ends and aircraft doors close.
