A lot of this is because there has traditionally been an imbalance between employer and employee, where if they stop exchanging labor for money the employer suffers a mild inconvenience while getting a new person hired, while the employee faces the possibility of losing access to food, shelter and medicine for them and their family.
This power imbalance means that the employee will often not complain about having wages stolen, complain about safety violations, or even be able to bargain fairly for the value of their labor. It's real hard to strike a fair business exchange with somebody who has a metaphorical gun pointed at your head.
Due to these unemployment benefits, that gun is gone for a lot of people, and they can push back harder and say that "no, the terms you are offering me for my labor is not good, I will not take this job" and the industries and businesses are losing their shit over this. Economical trouble and turmoil is for the "small people" to suffer, they shouldn't have to offer better wages to navigate a shifting economical landscape, they are entitled to cheap labor.
