In honor of National Custodian Worker’s Day on October 2, take a moment to appreciate the people who take care of the spaces around you. After all, even a city can be brought to its knees without efficient sanitation workers. They are as crucial as first responders to ensuring a livable city. The custodians who take care of building interiors and grounds are just as important. Our environments, large and small, will become intolerable rather quickly without regular maintenance.
