Things in the US are a bit different - for starters, there is not such thing as the Spanish “convenio”, thus companies are left to set their own terms, which, in most cases, is the bare minimum. Large unions do exist in the US, but again, they do not organise as their Spanish counterparts, as they only exist attached to a trade or industry. Thus, workers who want to organise, cannot just go and say “we are now represented by this or that union”, and if there is not an union to their trade, they would need to self organise into a small union, which obviously does not have the same bargaining power as a larger one, see the Starbucks employees unionising across the US.
