Professor John Pitcher pictured after the employment tribunal

A top Oxford University professor was forced to retire by college bosses in favour of diversity, an employment tribunal heard.

Professor John Pitcher wanted to carry on working as an English tutor and official fellow, but was told he would have to retire at 67 to help promote the university's 'diversity'.

A specialist in Shakespeare, Elizabethan and Jacobean literature and poetry, he had worked at the prestigious St John's The Baptist College in the University of Oxford for more than 36 years.

In December 2012 a retirement date was set for September 30, 2016, but Professor Pitcher was then made a Founder's Fellow on a fixed term from 2014 to 2020.

But Professor Pitcher, now 69, claims he was 'forcibly retired' on that date after the university and college applied a Employment Justified Retirement Age (EJRA) policy.

The college said the retirement was to 'safeguard the high standards' of the the university as well as 'inter-generational fairness' and to 'refresh the workforce'.

'Succession planning' and 'diversity' were also used to justify the move, an employment tribunal heard.

EJRAs were introduced after the default retirement age was scraped by the government in 2010.

The head of division at the university wrote to Professor Pritcher in 2014 with a notice of intended retirement date, and that it could be extended under EJRA.

A university panel met on January 26, 2016, and he was written to two month later stating his employment would not be extended to September 2020.

He appealed against that decision in March 2016, but that was rejected and a formal grievance was lodged.

A colleague at the university, Professor Denis Galligan, successfully challenged the EJRA principle at the appeal court, in which the university panel was heavily criticised.

Now Professor Pritcher is suing the college and university for unfair dismissal on the grounds of age discrimination.

He said in court documents submitted to Watford Employment Tribunal that the university knew its actions were discriminatory, but carried on because it was 'legally justified'.

Professor Pitcher said: 'I believe that decision was discriminatory because of age and was not justified and was also unfair.

'The EJRA for both the college and university which applied to me applied a retirement age of 67 years that retained the status quo from the mid-1980s.

'This age is far too low and I can see that I would be able to carry on working, as would many of my colleagues, well into my mid-70s.

'I felt it was unfair that I had to try and "convince" the university and college panels that my continued employment was appropriate.

'To be forced to reapply for my job by trying to satisfy an unreasonably high threshold test that I am virtually indispensable to the university when I had decades of impeccable service is degrading and humiliating.'

During part of the academic year from 2011 to 2012, Professor Pitcher was off sick after suffering a subdural haematoma and was unable to continue his research into 17th Century English poet and historian Samuel Daniel.

He claims the university appointed another tutor to take over his teaching duties on a five year contract before he was dismissed.

In 2014 he was awarded university distinction title and was given the right to be called a Professor.

Although he was the first Professor to have applied through the EJRA, two other professors have successfully appealed against the process since.

No other Russell Group university, except Cambridge, has retained a retirement age, the claimant's witness statement said.

Professor Pitcher added: 'None of these other institutions have reduced their standards by not forcibly retiring staff.

'There is no evidence to support the need to "refresh" the academic workforce in terms of turnover.

'The university is effectively seeking to justify discrimination on the grounds of age in order to promote equality and diversity of other protected characteristics.

'I fully accept the importance of equality and diversity. I am myself from a working class background and the importance of these kinds of social aims weighs strongly with me.

'I did not wish to retire, as I did not see the relevance of my age to my ability to carry out the duties of my post in research or teaching for the duties of the Founder's Fellow.'

Professor Pitcher claims he was let go despite raising more than £1 million in donations for the college.

Since the decision to enforce the initial retirement date, Professor Pitcher said he was removed from the university website and does not feature in online directory, and was offered unpaid Emerius status.

But Professor Maggie Snowling, President of the college and who chaired the panel that made the decision to retire Professor Pitcher, said the move had helped diversity.

In a witness statement, she said: 'I believe the decision not to accept the application John made was the right one.

'A decision not to allow John to work beyond his EJRA is not to question any of the work that he has done.

'The EJRA helped both the college and university take steps towards a more diverse academic body and will continue to do so.

'It is a proportionate means of ensuring increasing diversity and inter-generational fairness.'

Professor Pitcher, who lives in Oxford, is claiming more than £102,000 in loss of earnings from both his college and university salary over around 18 months.

He earned £83,000 a year for his official fellow and English tutor roles plus a housing allowance of £18,000.

The college argued he still receives support such as paying below market rent at college accommodation, college lunches and dinners as well as access to the library and a research allowance.

The tribunal continues.
