All kinds of policies and political decisions (made by any party or organisation, local or national) can end up with people losing jobs - increases in minimum/living wage might mean a struggling business can take on fewer people, say. Designating Liverpool as a city of culture and not Manchester means people in Liverpool have job opportunities not available in Manchester. Deciding to support the Ukrainian war effort means that (say) drone manufacturers do better than the firm making widgets for warships.
I realise that only one way of thinking is acceptable in this thread (that Labour are spiteful and vindictive idiots) and that my words will fall on barren ground, which is why I have largely given up commenting.
Save yourself, @CorneliaCupp - don’t get drawn in. There’s birds to be watched 😀
