Honestly, not sure ¯\_(ツ)_/¯ One of the reasons I wanted to remain in the EU was because of things like people-friendly labour laws - I trust the EU far more than I trust the government (regardless which party is in power).

AFAIK we are basically keeping everything from the EU at the time of severance, and I think the Brexit trade deal means we can't make any significant degredation of labour laws going forward. If anyone reading this knows different, please do correct me.
