Scottish workers are risking their health by putting in almost two hours of extra work after they leave the office, a survey has suggested.
Physiotherapists said that additional time spent on smartphones and laptops caused increased stress and musculoskeletal disorders such as back pain in people who carried on working after hours.
The survey for the Chartered Society of Physiotherapy (CSP) found nearly two-thirds - 64% - of office workers carried on working on electronic devices after they left the office, and spent an average of one hour 56 minutes doing so.
These stints came on top of an average of five hours 53 minutes in front of a screen in the office during their regular working day.
The UK averages were two hours 18 minutes of work at home after six hours 22 minutes in front of a screen in the office.
The online survey of 2010 office workers also found that just over half (53%) of office workers said their out of hours working had increased in the past two years.
But fewer than one in four people told the survey that they considered their posture when looking at screens outside of work.
The CSP warn that poor posture when using smartphones and other mobile devices, which many people do their additional work on, can lead to back and neck pain.
Lloyd Jones, CSP policy officer for Scotland, said: "Sickness absence can be devastating for the individual, and it can be very expensive for employers and society at large. Encouraging better working habits is in everyone's interest.
"A happy, healthy workforce is a productive one and it is very important that employers ensure they do what they can to look after the wellbeing of their staff."
