You could have Poland as an example. In 2000' we had high unemployment in horrible conditions because of mass trashdeal faux employment that won't give you anything like holidays, retirement, etc etc, you were entirely on the mercy of employer. Which was also illegal to employ people in full time on it, but no one ever was punished for it and we talk about millions of cases in long years.

Then a fucking PiS protofascist government noticed it's also putting entire country budget in shambles and will soon evolve into multipronged social crisis (succdems were ok with it) and someone there actually had a functioning brain for once and instead of delegalising it any further, they just taxed the trashdeals exactly the same as normal codex jobs. Employers mafia of course screamed bloody murder, but were ignored as political support for this was overwhelming and even the anti-union solidarność didn't sabotaged it, even if just because they are going on PiS leash for ages.

This caused the number of full-time trashdeals to drop dramatically, most of those people retained their jobs, but now were properly employed in codex deals (which clearly shows entire case to be just capitalist exploitation), unemployment dropped drastically and even economy improved.
