If you want to strengthen workers, create more demand for jobs, so that workers have options. By for example creating a successful VR industry, you create demand for more jobs that haven't previously existed, thereby empowering workers. Somebody who has previously been exploited to manufacture fridges can now give their boss the finger and go manufacture chips for VR headsets instead. One easy way to create more jobs is to hire a cleaning person, by the way. Everybody who is concerned about "living wages" and things like that should start by hiring cleaners and possibly gardeners for their homes.
I personally think the whole concept of "workers" is bunk. Everybody is a free agent entering contracts with other market participants. That's it. "Worker" is a social construct, actually, a socialist construct. More so, being a "worker" does not sound like a very desirable state of affairs, so I think society should work towards getting rid of workers.
It's not cut-and-dry bad the way we do things, but there is a lack of balance. There's a lot wrong that could be better if it wasn't someone's perverse bread and butter. Extreme wealth and power inequality, whether for people or companies, don't make for a just, healthy society.
