The head of one of the UK’s biggest disability charities is planning a legal challenge against the owners of the music business he founded in a dispute over its alleged failure to provide him with proper workplace support after a major illness. The pop producer Robin Millar, who is blind, said he had been denied a request for a support worker to assist him in his work after he faced mobility challenges following cancer surgery.

Millar, who until last year was the executive chair of the record label and publisher Blue Raincoat Music, said it was “an extraordinarily painful step to take” but he wanted to show even disabled people in senior roles could face “challenging workplace situations”. “You hope for loyalty.

You hope for humanity. You hope somebody says: ‘This matters.

Let’s sit down together and work out what support looks like.’ Too often that does not happen,” Millar said in a post on LinkedIn. Millar said that with “great reluctance” he had issued proceedings in the employment tribunal “relating to my experiences within the business I cofounded and its current ownership.

The claims include disability discrimination, victimisation and exclusion.” He added: “I have spent much of my life building inclusive businesses and advocating for disabled people, and I continue to believe something very simple: inclusion is not charity and it is not political correctness. It is good leadership, good culture and good business.” His instinct had always been to “minimise the personal impact of disability and simply keep going,” he said.
