In terms of leasing things out, the school I work for has an astroturf pitch which is leased out to junior football teams etc in the evenings. The sports hall is also used for sporting events already. I think a lot of schools already do this!
Any adult who comes into the school building whilst students are still present (bearing in mind we run after school clubs/revision etc) has to be escorted at all times unless they have a DBS check, so the times and facilities we can rent out are limited. There are often students on site until about 5pm, using the library and other facilities for revision, so letting people use facilities within the main school building is tricky.
If we wanted to rent out classrooms etc to make extra money during the week, it would mean potentially kicking students out of the building earlier- at a time when many of them are struggling!
The energy hikes schools are facing are absolutely massive- I have seen several heads and academy CEOs talking about costs increasing to 3-4x the previous winter.
The unfunded payrises are also a real issue. Academies could, theoretically, not give these to staff, but in reality, that will lead to staff leaving for other schools, and of course, a loss of goodwill among staff.
Every member of teaching staff is teaching a full timetable, some part time staff have had their hours cut. SLT and middle leadership are teaching more, which means they don't have time to carry out their other duties. TAs who leave aren't replaced- we have the bare minimum needed to cover ECHPs.
I genuinely don't know what the next step is, in terms of cutting costs. Do we lose members of staff like the librarian?
Last year, in a previous school, I was a union rep, and I was told the school had spent the majority of its reserves on agency supply staff (who were needed due to covid and general staff shortages). The school had also paid money to a local building firm to do essential work, and the firm then went bust, leaving the school in a very difficult position.
