What Does a Custodial Supervisor Do?
Keeping a campus clean can be routine and, at times, urgent, as when a pipe bursts before an exam or a stomach bug sweeps a residence hall. Custodial supervisors run the crews that clean schools, hospitals and offices and spend a lot of time inspecting buildings or covering staff gaps.
Also known as: Building Services Foreman, Housekeeping Supervisor, Building Services Supervisor, Custodial Services Supervisor, Building Services Superintendent, Custodial Services Assistant Supervisor
