On the Bristol Bus Company boycott:
At the time, the Bristol Omnibus Company was notorious for racial discrimination in recruitment. Hackett says labourers from the colonies and former colonies were allowed to “wash the buses at night”, but barred from the better-paid work on the bus crews. This segregation was not only upheld by the bus company, but also vigorously defended by the local branch of the Transport and General Workers’ Union, which did not want its members to lose jobs to immigrants.
They even point out that it was a nationalised company too. government and unions, at the time, being more racist that the society around both. Good on them for actually telling the story straight.
