We have implemented a policy to have employees that feel under the weather to stay home. We are practicing social distancing and consistent hand washing. Employees have been informed to avoid areas with 10 or more people if a 6 foot perimeter is not available. Our janitorial department is continuing to be diligent in cleaning all public areas and are accommodating contracted clients in detailed/ additional disinfecting cleaning requests.  We are keeping up with the government recommendations to make sure we are doing our part to ensure the health of our employees, clients and accounts.
