Bosses should make the workplace a more cheery environment to help ease workers past their post-holiday blues.
Behavioural and personality psychologist Donna Dawson - who has appeared on a number of TV programmes such as This Morning - has said that workers in large organisations might find it easier to ease themselves back into work after a summer getaway.
However, small business bosses should combat the ill-effects of post-holiday blues as they can be more apparent in a small organisation.
"Holiday blues probably could have an affect on small business and it's more noticeable too," she commented.
Ms Dawson also noted that it can take a day or two for people to adjust back to their normal working routine.
Research conducted by Birmingham International Airport found that two-thirds of passengers feel the pinch of post-holiday blues.
One in sixteen people will phone in sick within the first two weeks back at work while one in eight admitted to making an excuse up so that they could stay in bed rather than go straight to work.
