People could improve their health at work if they were to increase their activity levels.
This is according to the Chartered Society of Physiotherapy, which has noted that the first Monday in February is the day when most people are likely to ring in sick to work.
In a bid to counter this, the physiotherapists are encouraging workers to become more active by doing things like taking exercise classes at lunchtime.
People were also advised to carry out stretches at their desks and take 'micro-breaks' to walk away from their desk on a regular basis.
Clare Claridge, chartered physiotherapist, commented: "Exercise is an excellent way to improve your health and help your state of mind.
"There's nothing worse than being cooped up in an office behind a desk all day for your mental and physical well-being."
The society's own research revealed that 25 per cent of employees regularly work all day without taking a break and 46 per cent reported that their physical pains were due to being in the same position for too long.
