I’m sorry, but in all of these type of stories are people forgetting their are likely thousands of businesses locally that would likely have the same or similar roles available with full time perks.
If your not happy with your lot in life, change it, I dropped my career, went back to university, got a degree and tripled my base income.
Honestly, I don’t blame Nintendo or any other company using contractors for lower level or seasonal positions.
Nintendo made a choice, the workers made theirs. If either have a problem with that, part ways and get a better fit.
