It appears that Unison and Donald Trump agree about workers rights in the UK. Trump has imposed tariffs on the UK due to claims that it does not do enough against forced labour. This from a nation that has worse workers rights than the UK and makes use of illegal immigrants in work (therefore avoiding employment laws) more than the UK does.
The video is about workers rights which unions have won, rights that many in the USA do not have. It is out of date as Labour, under Starmer, gave workers even more rights.
