I went to a school in the middle of 2 deprived council estates.
In one of our classes, we were taught a bit about trade unions. Teacher asked us if we had a parent who was in a trade union. When we all looked blank as if he’d just asked had we been to the moon - he asked in a louder voice :
Well, come on, this is a part of the city where people have working jobs. Is anyone’s parent in a trade union?
looking back, do you think he used the phrase ‘working jobs’ because it sounds more tactful than saying “this is a working class area?”
