According to Living Streets, walking to work is beneficial for the health and mental wellbeing of employees as it provides physical activity, fresh air and relaxation.
The organisation has launched a new campaign called Walking Works to promote the benefits of walking to commuters across the country.
It cites a study which suggests that employers can cut staff absenteeism by up to half if their workers take part in 90 minutes of exercise a week.
Tony Armstrong, chief executive of Living Streets, said the average employee took seven days off sick in 2006, costing the UK economy £13.4 billion.
"Improving the health of those working in your organisation is a real and worthwhile way to reduce this burden," he remarked.
Earlier this year, the sustainable transport charity Sustrans launched a similar campaign to get more employees cycling to work.
