When I joined the Labour Party, I joined a movement founded by trade unions.
When I became a Labour MP, I was elected on a promise to join workers on the picket line.
Supporting those on strike isn't a matter of strategy. It's a matter of principle.
Industrial action is almost always covered like this, as if workers are somehow separate and distinct from the rest of the public rather than one and the same. What about workers who've missed operations due to long hours or holidays because of low pay?
