If the BBC wants to give people from less advantaged backgrounds more opportunities, it starts by making *REAL CONTRACTS* available to them. My first four years at the BBC were spent not knowing if I had work one month to the next. https://www.dailymail.co.uk/news/article-8817291/BBC-boss-Tim-Davie-says-corporations-obsession-Oxbridge-end.html
For working class people, the way the BBC treats employment status presents an unacceptable level of risk and closes the door. Only possible for me at first as parents' lived close to London, and my Dad's job on the tube gave me heavily discounted rail fares.
Even later in my career there I joked that my contract was treated like that of an aging goalkeeper, propped up a year at a time so long as I was still standing and was a safe pair of hands. Stunts growth, salary, pension-- everything. Sort it.
