I don't really think this is about laws, but even in that arena, companies already do their best to avoid those within the US, nevermind internationally. See e.g. recent Patreon controversy for an example of this. There's man others. So I don't really think law is the problem here.

This is the real issue and unfortunately these are finely weaved deep inside US corporate culture itself - they're part of culture fit for hiring in US multinationals and are thus highly unlikely to ever be disrupted from within the workforce of those companies.
