Why the holiday period needs its own plan
During term the arrangement is stable: the same cleaner, the same rooms, the same hours. In a holiday period the crew is larger, the tasks are different, the equipment is heavier and the areas being worked change daily. Add a painter, an electrician and a flooring contractor and the site becomes a small project rather than a cleaning round, with all the coordination that implies.
The access picture changes too. During term, staff presence provides an informal control on who is in the building. In holidays that control disappears while contractor traffic increases, which is the opposite of what you would design. A written plan naming who is on site each day, and an arrangement for keys and alarms, restores the visibility that term-time presence provided. Agreeing the daily notification format before the break, even as a short message, removes the need for anyone to chase it while the works are running.
