This is the same press release from the union as at https://news.ycombinator.com/item?id=48663861, and the same discussion points apply as there, including the fact that the press release is conflating 'Wikipedia Workers' and 'British-based employees at the Wikimedia Foundation'. The two are not the same.
This conflation appears to be the fault of the union. Certainly the people who write Wikipedia well know the difference between themselves and the Wikimedia Foundation staff.
