Yes, you would be compelled to support union actions, such as job action in support of collective goals you don't agree with, and get to pay for the right to do so as well. You would not be allowed to negotiate individual concessions for work or skill beyond the norm. Everyone is even more focused on "fair outcomes" (read: the same) than in any non-union environment.

We're not interchangeable cogs in some manufacturing machine; we're extremely skilled experts in the biggest seller's market of our careers. Why anyone would want to unionize right now is beyond me.
