ISSA has released a new analysis of data which strongly supports the position that cleaning is economically efficient and, thus, a relatively modest investment in improved cleaning produces substantial returns.
The following is an excerpt from the paper:
One of the many benefits of a clean facility is the reduction of harmful contaminants in the indoor environment. A clean and hygienic facility gives building occupants a visual comfort level and reduces potential risks that may be associated with buildings that are not as clean. Although there are many studies that address improved indoor air quality and the risks associated with dust and bacteria on surfaces, few have demonstrated how health risks due to inadequate cleaning impact building occupant personnel costs and, ultimately, a business’s bottom line.
The research that follows addresses the connection between cleaning and the spread of illness, which manifests itself in employee lost work days (absenteeism). Absenteeism is a substantial cost to businesses that can be reduced through proper cleaning practices.
An Absent Management Study was conducted in 2011 by Chartered Institute of Personnel and Development (CIPD) (The Chartered Institute of Personnel and Development, 2011). CIPD is an internationally recognized company with more than 135,000 members across 120 countries. It is one of the world’s largest human resource organizations.
The CIPD study gathered data from 592 organizations across the UK, employing more than 2 million employees. The study documented the average days of absenteeism per employee in a variety of work settings, along with their estimated costs to employers. The average sick days per employee per year were 7.7 days (Table 1). CIPD determined the average cost of absences to be £673 ($869 USD) per employee per year. Illnesses such as colds, flu, stomach upsets, and headaches were the most common cause of short-term absences.

A study published in the Journal of Occupational and Environmental Medicine in 2003 reported that, based on a random sample of 28,902 United States workers, health-related lost productive time (LPT) costs employers $225.8 billion per year, or $1,685 per employee per year(Stewart, 2003).
That study calculated absenteeism as the sum of hours per week absent from work for a health-related reason. Cost impact is estimated by multiplying lost productive time (absence hours plus hours lost from reduced performance) by the individual worker’s hourly labor cost. This is the recommended method of calculating the basic impact of absenteeism and its cost to the organization.
Hidden Costs of Absenteeism
While some organizations may track worker absenteeism, thus providing preliminary data useful in connecting cleaning impact on personnel costs, they may be missing all the absenteeism costs involved.
A 2008 survey conducted by Mercer/Marsh (Kronos Consulting & Mercer, LLC., 2008) identified the hidden costs of absenteeism. The survey found that, in addition to the payroll cost of the absent employee, organizations must hire temporary labor or offer overtime to cover the absent employee’s responsibilities and that the “hidden costs” should be factored into absenteeism calculations. To do so, multiply the additional hourly costs by the number of hours incurred and add this figure to the absent employee’s direct costs.
The survey also revealed that many employers fail to account for the 36 percent in administrative expenses that it takes to manage absence benefits. This includes tracking, reviewing, and processing the absence by company staff. Once that cost is determined, often as an annual percentage, it can be evenly divided by the total number of employees to determine the average per employee. It then is added to the average direct and indirect labor costs above, per employee.
Still more impact was revealed by the Mercer/Marsh survey: the disruption in the labor supply affects productivity, even with replacement staff. This could lead to lost sales, late delivery of goods/services, customer dissatisfaction and loss of revenue. Respondents to the survey reported that unplanned absences caused a 54 percent decrease in productivity/output and a 39 percent drop in sales/customer service. If an organization can estimate these additional costs, the annual average cost of lost revenue per employee then would be increased.
1 A 5 percent trimmed mean was used because the large standard deviation shows there is high variation across organizations, with some reporting extremely high levels of absence. In 2010 the arithmetic mean was used because the standard deviation was within acceptable limits, showing less variation in the absences reported by organizations. Table 1 includes the mean and 5 percent trimmed mean for reference.
