Gallimore said that staff at the school faced losing both their jobs along with the unpaid wages.
“Despite these circumstances, staff have continued to turn up each day, placing the needs of pupils above their own personal and financial uncertainty,” she added.
“If there is one positive story to emerge from this situation, it is the extraordinary professionalism, loyalty and care shown by the people who have made Abbotsholme what it is.”
In his letter, Costigan said the school would remain fully open until 22 June.
His immediate priority, he added, was to ensure all pupils – particularly those sitting exams – were able to finish their studies with the minimum possible disruption.
“The pupils, staff and wider Abbotsholme community remain at the forefront of all discussions, and we are working hard to identify the best possible way forward,” he said.
The MP for Burton and Uttoxeter, Jacob Collier, said he was aware of the school’s impending closure and was in touch with the Department for Education and teaching unions.
“This is particularly worrying for staff who have reportedly not been paid for months and students ahead of exam season,” he said.
