In this case the issue seem to be a debate around specifically what types of work these people were permitted to perform on their visas, with the union arguing, in their self-interest, that the work they were doing did not qualify.

If teenage me had been dragged aside and asked to prove I'm legal to work I have nothing. Where am I staying? Well I have a hotel reservation. OK, and how are you paying? Well here's a photocopy of my English boss' Amex that'll work right?
Everything was fine of course, as far as I know it was entirely legal, I was the foreign employee of a huge US firm, temporarily in the country to train people, by the time I left I had my own Amex and the hotel was paid with that, I was waved through both borders, no problem. But I had no proof of any sort, if you had wanted to detain me and insist you need documentation I had none. Maybe my bosses could have cleared it up? I just assumed it would be fine, and it was.
In 2025 I wouldn't recommend travelling to the US. A friend went, rich white guy with his very normal family, no doubt nothing seemed weird for them but if he'd asked me whether it's a good idea I'd say "No".
This seems less likely, because most places have some form of 'business' visa that's about as easy to get as a personal travel visa (the US's one is under the visa waiver program where available, say). The catch is that the definition of 'business' tends to be restrictive and unclear.
I've never done this, despite having worked abroad on a few occasions. When my visa ran out and I had to apply out of the country, I went home and applied and a few months later went back.
They literally don't believe you when you explain that this is false of the law in general, and especially false of immigration law, which is deliberately designed to have tons of ambiguity and discretion in it, to enable selective enforcement and keep guest workers afraid and exploitable in their ambiguous status.
