During winter 2015, a trial was completed for a major international insurance company in Auckland, New Zealand. The trial was conducted in a 100-seat call center and included a monthly Antimicrobial Surface Treatment of all working areas (workstations, equipment, and common areas) and supply of the GermFree24 Hand Protectant in-wall dispensers for staff use. The trial was measured by comparing absenteeism rates against data from the past 3 years (2012, 2013 and 2014). The trial was extremely successful. Absenteeism was shown to drop by as much as 50% during the winter period, and over 30% against the 3-year combined average.
