Four maths lecturers dismissed by a Midland college are to take their case to an employment tribunal.
And their former colleagues at Halesowen College are to step up their campaign over the dismissals by refusing to recognise lesson observations from March 25.
The dispute began with the dismissal of maths lecturer and University and College Union branch chair Dave Muritu on the day before the college closed for Christmas.
In January three other maths lecturers, who were also active union members, were sacked and later lost their appeals along with Mr Muritu.
UCU leaders claimed replacement lecturers were appointed by the college in October – two months before the quartet were sacked or had the chance to appeal against their dismissals.
UCU regional official Nick Varney said: “At all the appeals, the employer did not have enough evidence against the individuals to dismiss them and used students’ failure to achieve certain levels of attainment as a basis for sacking them.”
College principal Keith Bate said the lecturers had been dismissed following internal procedures and that the decisions were final.
