Few buildings work as hard as a school. Hundreds of students pass through the same doors, share the same taps and lean on the same desks, and in a kinder or childcare room the youngest kids touch everything at floor level. Cleaning that drops off for a week shows up fast in sticky tables, overflowing bins and toilet blocks that parents talk about at the gate.
Business managers and centre directors have a second concern. The people in your rooms after dark need to be checked, consistent and known. A new face every fortnight is not good enough around children.
Holidays bring their own squeeze. The breaks are the only real chance for floors, carpets and windows, and if nobody has planned the work by the last week of term, it gets pushed to the next break.
