According to CCH Incorporated (a company that produces electronic and print products for the tax, legal, securities, insurance, human resources, health care, and small business markets) unscheduled absenteeism can cost up to an average of $602 per employee, per year.  Considering most employers offer on average 5 sick days per year, this means that each sick day costs more than $120.  This cost does not include indirect costs such as overtime pay for other employees, hiring temps, missed deadlines, lost sales, sinking morale and lower productivity. Indirect costs can add up to 25 percent to the direct costs, according to Employee Benefit News and HR News stretching the cost of a sick day to more that $150! http://humanresources.about.com/od/laborrelations/a/sickleaveabuse.htm

It has been overwhelmingly documented in the wake of the HINI pandemic that a properly cleaned office space results in fewer sick employees.  Thorough cleaning hinders the spread of vectors via touch points on office surfaces such as door handles and other commonly touched surfaces.

Having read the statements above, it is easy to make a case that a properly cleaned office space will save the operation money over the course of a year.  The next time you put your office cleaning services out for tender, think twice before accepting the lowest bid.   Remember that if by spending an extra $100 dollars per month, and you prevent even one employee sick day per month, you are saving $50.
