It has been wild to see this making the rounds on the BBC and elsewhere, but Game Workers Unite has founded a UK branch and is taking sign-ups starting from 15/12/2018 (I am using UK date formatting because this is a UK story – I will be taking no future questions at this time).
You can find their Twitter account here & some articles that have been circulating about them below.
(P.S. Last link requires a BBC account.)
I am mostly sharing here to let folks who didn’t catch this become aware of it – GWU UK is not the first games union, but it is important to have, and keep, eyes on it as it develops so we can know to have folks’ back where necessary.
