As a UBI proponent, I will offer this in rebuttal. If you give labor additional negotiating power over capital, (the two coarsely defined players in this game) you will see shortages, and capital will lose a lot of value. This includes the middle class, who saved up peanuts and now have to pay people real money to do work. Those people will genuinely get screwed. Hyperinflation is a real possibility, and UBI needs to be tuned pretty tightly to prevent it.
