"worker", singular. And the rest?
When the media so blatantly cherry-pick what they choose to report and what they turn a blind eye to, can such a misinformed society really be called a democracy?
Its not misinformation vs the governments word. Its misinformation vs populist pseudo-fascist misinformation.
If the government is telling you or us that these workers did not have valid visas, that probably means that at least some definitely did have valid visas.
