Researchers have uncovered a clear link between high levels of sickness leave and levels of job satisfaction and job involvement. The study, carried out by Juergen Wegge, revealed that sickies cost the UK economy between ?10 and ?12 billion every year. Wegge also stated that understanding the cause of absence is the best way for a company to root out staff who regularly call in sick with excuses. So if you’re looking for a way to boost productivity and alleviate the sickie epidemic it might be time to make your colleagues happy in their jobs.
