New research reveals that 32% of employers report stress, anxiety, depression or other mental health problems as a key reason for employee sickness absence.
Survey findings highlight absence trends
The YouGov survey, commissioned by Acas, asked employers to identify the top three reasons staff give for being off work.
While mental health concerns were significant, 62% of employers said absences were due to minor illnesses such as coughs, colds and flu, and 23% cited headaches and migraines.
The findings come ahead of changes to statutory sick pay under the Employment Rights Act 2025. From 6 April 2026, workers will be eligible for sick pay from the first day of illness rather than the fourth, and the minimum earnings threshold will be removed.
Acas calls for healthier workplaces
Julie Dennis, Head of Inclusivity at Acas, said: “Our findings reveal that 1 in 3 bosses report mental health problems as a key reason for staff absence. It is a surprising result, alongside the top reason for sickness being coughs, colds, flu and other minor illnesses.
“Bosses need to ensure that their work environments are healthy places to work, as well as prepare for the new rules on sick pay that will be coming in a few weeks’ time.
“Workers should also look after their own health and wellbeing too. If they are experiencing stress, they should talk to their manager as soon as they can. Acas has good practice advice and training in this area.”
Acas recommends providing manager training, offering flexible working, ensuring access to mediation services, and maintaining clear absence policies. Updated guidance reflects the upcoming legal changes and supports organisations in managing sickness absence effectively.
