1. Fight ageism (every 20 year old today will grow up someday)
2. Fight open office layout (my opinion, may not be shared by everyone)
3. Fight for equal pay, discriminations of various sorts
4. Fight for reasonable share in success and against the massive differential between CxO and others' pay
5. Resist outsourcing where it makes sense
....... the list goes on ....
In Poland, worker unions at various companies strongly block any attempts at automation, because it makes less people are required to do the job so it leads to layoffs. But without adopting automation, in the long run the company can't keep up with automation-heavy competitors, so they go out of business, making everyone lose their jobs.
This is, I believe, the biggest strike against unions. If the unions decide you don't get open offices, then that decision binds everyone, whether they wanted an open office or not.
You just have to hope that the many tradeoffs you make are worth the things you get in return.
Having management make adaptations specific to an individual's preferences is a feature available in a management-employee negotiated arrangement that might be precluded or more difficult in a union shop.
As examples, I have colleagues working from remote locations, colleagues working in co-working spaces, colleagues working non-traditional schedules (by their choice, not mine). I can't see how having a union policy on work schedules and rules would have helped any of those employees and can easily see how they'd be harmed by having standardized work rules.
Not clear why a talented and hard working person of one gender would be opposed that a similar person of another gender get same pay?
It did not refer to people making unequal contributions.
Because there might not be an even distribution of people with certain skills. For instance, some point to the disproportionately large number of Asians in higher paying roles, and demand a form of equalization.
The issue is not that people don't believe in equality, it's that people don't have the same view of what is equal. In particular, some view equality in terms of equality of outcomes while others view it in terms of equality of opportunity.
