Yeah, well, the whole thing has been a "slow boiling of the frog" over 2 - 3 decades of weakening worker rights and this is coming quite late when things are so bad that literally the majority of young adults are unable to actually find proper jobs and are stuck in an endless chain of exploitative part-time contracts were the rules that say that somebody is supposed to become a permanent employee after 2 years of such contracts in the same place are usually just bypassed by, for example, not giving somebody a contract for a week or two when they're approaching that threshold.
And don't get me started on fake "outsourcing" shit like Uber deliveries.
De facto, worker rights in Portugal are already worse than in most of Europe for those who have entered the job market in the last couple of decades and not that far away from the shit-show in the US, it's just that in practice there are two classes of workers roughly divided by age and the ones on the side with the steady jobs haven't lifted a finger to fight for the rights of the ones who can't actually get a job, only "work".
All this shit, by the way, supported by mainstream politicians of both of the largest parties, even the supposedly (but not at all, as they're Neoliberals above all nowadays) left-of-center one. Mind you, the ones currently in government are the rightmost of both who have been going to the UK to see what the Tories over there did (and from living there I can tell you those types are hard-right Neoliberals/Posh-Fascists) hence this push for getting us over the fence towards an even more American model, same as the Tories have been doing in Britain.
By the way next door Spain has a similar situation because they've adopted similar legislation for part-time contracts at roughly the same time.
Still, better late than never, but maybe not so much better.
