I think Greg Wallace will find that the reason people working on his shows have not made any complaints is because the power is not with them. Freelance workers in the entertainment business can’t afford to get a name as a trouble maker or they won’t be working. No complaints made does not mean there was nothing to complain about.
As for middle class women of a certain age? Ooh Greg, showing your misogynistic, ageist petticoats.
