More than 40 support staff at a secondary school are facing redundancy.
A consultation has begun at Longslade Community College, in Birstall, after it was announced a number of jobs were under threat.
Positions which could be axed include canteen, administration and premises staff.
Acting head teacher Jason Smith said the potential job losses were due to a reduction in pupil numbers.
He said: "In September, The Martin High School, in Anstey, changed to an 11 to 16 site, resulting in Longslade's year 10 intake reducing by around 187 students. Longslade has traditionally been a large upper school and sixth form with intakes of 400 pupils per year group.
"We have about 160 pupils starting in year 10 this September, making about a 53 per cent reduction in student numbers overall.
"Therefore, a reduction in our associate staff is something we are consulting on."
Mr Smith said the number of teachers at the school had been "managed through natural reduction", with staff not being replaced once they left and through shorter contracts.
"The redundancies will only affect associate staff," he said.
Any redundancies, should they go ahead, will not take place until January.
Union leaders have been notified and the consultation period will last 45 days.
Mr Smith said: "We realise this is a difficult time for some staff but at this stage this is a consultation and not a fait accompli."
Longslade, which takes pupils aged 14 to 18, is hoping to become part of a multi-academy trust led by Beauchamp College, in Oadby.
The move could pave the way for all-through education – with children staying at the same school from the age of 11 to 18 – in Birstall, as long-term plans include merging Longslade and Stonehill High.
Stonehill High, which takes pupils aged 11 to 14, shares the same site as Longslade.
Mr Smith said the school was concentrating on improving standards and becoming part of the trust was unlikely to happen until then.
The school is rated inadequate by Ofsted, despite 60 per cent of pupils gaining five or more GCSEs at grades A to C, including English and maths, last summer – up 21 per cent on the previous year.
A recent monitoring inspection found improvements. Another inspection is due to take place before the end of the academic year.
Chairman of governors Tony Stott said: "We recognise this is a very difficult time for everybody and we need to be sensitive to that.
"It's clear a restructure is required and must be done with the best interests of the school and its students in mind.
"Longslade is making improvements and we hope that's recognised by Ofsted again at its next inspection.
"We have more robust systems in place and we're moving forward positively."
