Biomedical Science Workers at Lancashire Hospitals Launch 20-Day Strike Over Holiday Pay Dispute

Biomedical science workers at Blackburn and Burnley hospitals will conduct 20 days of strikes between June 15 and July 10 over thousands of pounds in unpaid holiday pay, according to Unite union. The strikes will occur in four separate periods across blood testing departments at both Lancashire Teaching Hospitals Trust sites, affecting urgent and routine diagnostic services for patients.

Unite union claims the trust owes staff in the biomedical sciences department compensation for improperly calculated holiday pay on shift work. The dispute centers on workers whose pay varies across different shifts, requiring holiday calculations based on average earnings rather than base pay rates under UK employment law.

Strike Schedule and Affected Services

The industrial action will unfold in four waves: June 15-19, June 22-26, June 29-July 3, and July 6-10. Workers conduct urgent and routine blood tests alongside broader diagnostic work at both hospital sites. A Lancashire Teaching Hospitals Trust spokesperson said the organization is developing a comprehensive plan to mitigate patient impact during the strikes.

The timing follows a major pathology services merger completed April 1, 2026, which consolidated laboratory operations from four NHS trusts—Lancashire Teaching Hospitals, Blackpool Teaching Hospitals, East Lancashire Hospitals, and University Hospitals of Morecambe Bay—into a single network under Lancashire Teaching Hospitals leadership. All staff from the blood sciences department at East Lancashire Hospitals became Lancashire Teaching Hospitals employees as part of that transition.

Tribunal History and Management Conduct

Unite asserts the trust lost a tribunal over a similar holiday pay dispute several years ago but failed to settle the issue for remaining affected employees. "Staffing issues at the biomedical sciences laboratories have already put staff under strain but the refusal to pay what staff are legally entitled to is adding insult to injury," said Sharon Graham, Unite general secretary, in the union's statement. "Staff at the hospital have exhausted all avenues and are now left with no choice but to strike."

The trust confirmed that affected workers filed a grievance with their former employer at East Lancashire Hospitals before the April 2026 merger. An appeal hearing is scheduled for late June 2026 and will be conducted by Lancashire Teaching Hospitals management. The trust has not disclosed the total amount in dispute or the number of workers involved.

Holiday pay calculations for shift workers frequently become points of contention in UK healthcare settings. Workers whose earnings fluctuate due to night differentials, weekend premiums, or rotating schedules are legally entitled to holiday pay calculated on average earnings over a reference period, not base hourly rates. Employers who calculate holiday pay using only base rates systematically underpay shift workers, and the accumulated shortfalls can reach thousands of pounds per employee over multiple years.

Union Strategy and Worker Use

The 20-day strike represents one of the longest continuous industrial actions in UK healthcare laboratory settings this year. Unlike strike authorization votes that position workers for potential action, this dispute has moved directly to walkouts after exhausting internal grievance procedures. The extended duration and multiple strike periods suggest Unite is applying sustained pressure during the trust's appeal process rather than conducting brief symbolic actions.

Laboratory workers hold significant operational use in hospital systems. Blood testing departments process samples for emergency medicine, surgery, intensive care, and outpatient clinics. Delays in diagnostic results can cascade through multiple departments and affect patient discharge planning, surgical scheduling, and critical care monitoring. The trust's statement about developing mitigation plans likely involves contingency staffing arrangements, prioritization protocols for urgent tests, and potential sample routing to other laboratory facilities in the regional network.

The strike occurs as the newly merged pathology service navigates its first months of consolidated operations. Integration of four separate laboratory systems typically involves standardizing equipment, harmonizing testing protocols, and unifying staff policies—processes that can strain existing workforces before efficiency gains materialize.

What This Means for Union Members

This dispute illustrates how organizational restructuring can become a pressure point for resolving longstanding grievances. Workers at East Lancashire Hospitals filed their original complaint with their former employer, but the April 2026 merger transferred both the workforce and the unresolved dispute to Lancashire Teaching Hospitals management. The scheduled late-June appeal gives the new employer an opportunity to settle before the final two strike periods, but Unite's decision to announce all 20 strike days simultaneously signals the union expects management to drag out the process without worker pressure.

The case demonstrates the strategic value of documented tribunal wins in subsequent workplace disputes. Unite references the trust's earlier tribunal loss on similar holiday pay issues, establishing a legal precedent that strengthens the union's position. Organizers in healthcare settings should treat tribunal victories as organizing tools, not just individual remedies—they create use for systemic grievances affecting multiple workers under the same policy.

For healthcare workers on variable-pay schedules, this strike underscores the importance of auditing holiday pay calculations independently. Shift workers, on-call staff, and employees with regular overtime or premium-pay components should request itemized holiday pay records and compare them against average earnings over the statutory reference period. Employers who miscalculate holiday pay for one worker typically apply the same flawed formula across entire departments, making individual grievances into collective claims that justify union action.
