Acas: Mental Health Problems Among Top Three Reasons for Staff Absence

Why It Matters

With mental health now a leading driver of absence, the upcoming SSP reforms will increase employer costs and pressure firms to address wellbeing, making proactive support a competitive necessity.

Key Takeaways

• Mental health drives ~33% of reported staff absences.
• New SSP starts day one, 80% pay, $156.5 flat.
• Flexible work and manager training can cut absenteeism.
• Wellbeing investment alone insufficient without tailored support.
• Expanded SSP eligibility reaches more part‑time workers.

Pulse Analysis

Mental‑health concerns have surged to the forefront of workplace absenteeism, with Acas reporting that about one‑third of managers identify stress, anxiety or depression as a primary cause of sick leave. This mirrors broader European trends where mental‑health‑related absence costs employers billions annually in lost productivity, higher turnover and increased health‑care spending. Companies that ignore these signals risk not only higher direct costs but also erosion of employee engagement and brand reputation.

The statutory sick pay overhaul slated for 6 April 2026 intensifies the financial stakes. By shifting SSP eligibility to the first day of illness and offering 80 % of normal earnings—or a flat £123.25 (≈$156.5) whichever is lower—the government removes the lower‑earnings threshold, pulling many part‑time and gig workers into the scheme. Employers can expect a rise in short‑term payout obligations, prompting a reassessment of budgeting for absence management and a push toward preventive health strategies.

Acas’s recommendations focus on proactive, tailored interventions. Flexible working arrangements, robust manager‑training programs, and clear, accessible absence policies can mitigate mental‑health‑driven leave. Moreover, investing in customized wellbeing offerings—beyond generic benefits—helps align support with employee preferences, driving morale, retention and ultimately, productivity gains. Firms that embed these practices are likely to see reduced absenteeism, lower SSP outlays, and a stronger competitive edge in talent acquisition.
