The head of a school trust embroiled in a row over classes about LGBT rights says staff have been left "distraught".
The No Outsiders programme at Parkfield Community School in Birmingham has been paused after protests by parents.
Hazel Pulley, chief executive officer of the trust which runs the school, said some staff had lost weight and were not sleeping.
She added the situation had been the most "challenging" she has seen in 27 years in education.
There have been protests outside the school in Alum Rock over No Outsiders, with some parents claiming the lessons were age-inappropriate and incompatible with Islam.
Ms Pulley, of Excelsior Multi-Academy Trust, confirmed its lessons have been temporarily stopped to allow for discussions with parents.
The Leigh Trust has also said it would be halting lessons at four of its schools until reaching an agreement with parents. [BBC] Read more
