PPP healthcare has called in TV comics Mel Smith and Griff Rhys-Jones to promote its Employee Support service.
The comedy duo appear in a five-minute video for company directors explaining the benefits of the service with a talking heads' routine.
Employee Support is an extension of PPP's healthcare's group health scheme and provides stress and psychological counselling.
A 24-hour confidential phone hotline provides professional counselling.
It is designed to reduce staff absence and improve workforce efficiency.
Figures from the CBI and mental health charity Mind show that, on average, employees lose 2.5 working days a year due to stress. This is equal to an average cost of £158 per employee a year.
PPP healthcare new corporate services director Keith Trower says: "Company directors need to appreciate the importance of stress and understand how it can be prevented and managed."
Employee Support has four tiers – option 1 offers confidential stress counselling, option 2 adds legal and financial information, option 3 adds referral to a chartered clinical psychologist and option 4 offers short-term professional counselling.
PPP was bought by Guardian Royal Exchange at the end of last year in a £435m deal.
