I feel like there’s still a lot of unexplained jargon here. Perhaps you’re just wanting to keep it short and give a starting point for further research, if so, all good.
I’m thinking things like:
You explain Right To Work laws prevent Union Security Agreements. But don’t explain what those are.
There is a brief mention of illegal reasons to be fired, but it’s not really enough for someone to work out if they have been illegally fired
The standard for just-cause could be explained more, or linked to more info
Maybe the above points could have a link to another website that explains them?
I also feel like some things should have sources. For example, that Right to Work was misleadingly named for political purposes, that unionized workplaces get higher pay, that you can’t be fired for unionizing, the likely outcome of an NLRB judgment. I’m not saying these things are wrong, in fact they could be easy to find a source for, all the more reason to do so.
This is just some feedback, feel free to ignore, but I think if it were me reading I would appreciate links to more info and to back up claims as it would help me trust it a bit more.
