What does "up to a point" mean? Like these videos, this makes it sound as if the progress of workers' rights is over, and we've got all we'll ever need.
What about, say, "a living wage", which the government's minimum wage law is unable to provide? This isn't done. It will probably never be done.
Governments need to pursue policies to ensure there are a surplus of jobs paying living wages for the number of workers that need to live off work. This is not the same as pursuing policies to ensure every job pays a minimum wage.
Now, I’m somewhere in the middle. I think shipping jobs overseas has had a catastrophic impact on wages and jobs (unions can’t protect against this in any meaningful way). Also unions will milk a company dry regardless of consequences. But they occasionally protect against some abuse. On the other hand they stifle innovation in very counterproductive ways.
On the flip side this is also what has contributed so much to global progress in terms of increased wages globally, increased standard of living, life expectancy, literacy levels, and every other measurable positive progress indicator. I'm conflicted as well.
The same can be said of corporations too.
So fighting against unions is the same as fighting against people's right to associate since any group can have the same shortcomings unions do.
That point being when capitalists convinced the government to limit the power of unions and stifle their use of union pension funds to finance things that would be beneficial union.

But, like all big and complex organizations they become corrupted and rather than having the interest of workers and society as foremost goals, self perpetuation and preservation become the goals.
Except for Bernie no other candidate explicitly and implicitly supports unions. All the others support policies which would undermine unions, except for where it’s politically expedient.
But this is natural. Even in the proletarian era of Mao, unions/workers suffered descent too. Often a most favored group would be pitted against another when necessary, for example the Hong Wei Bings [紅衛兵]
