NHS Lanarkshire's Occupational Health & Safety division has been awarded a new contract.
Salus will co-ordinate a pilot project in Scotland which helps people return to work following sickness.
The government's Department for Work and Pensions ' new Fit for Work Scheme will involve employers, GP's and local councils in helping people with medical conditions or disabilities to work
The scheme was launched at Salus' Coatbridge headquarters by Dame Carol Black, National Director for health and work.
She said, "There is good, strong evidence that shows working is good for your health. The Fit for Work pilot aims to help people who may be struggling to stay in work - perhaps due to stress, family problems, bereavement or back pain.
Salus, which is owned and operated by NHS Lanarkshire, has been awarded the contract for the Scotland-wide programme.
Mark Kennedy, Return to Work Services Director at Salus said, "The programme is called Working Health Services Scotland. It will support people who have been absent from work, through sickness or disability and help them return to their job.
The pilot will be predominantly for people employed by small to medium sized enterprises who have no occupational health services of their own.
Salus has been providing this service in the Lanarkshire area for more than five years and this model has been recognised as an innovative approach for Scotland. Every health board in Scotland is working in partnership to ensure a Scotland-wide service.
Salus received funding from the DWP and the Scottish Government to run the pilot in Scotland until March 2011 when it will be reviewed. Businesses or employees wishing to utilise the service shoulod call 0800 019 2211"
