I have heard about companies doing this in times of economic downturns to prevent layoffs. If that was the cause and it was communicated as such and temporary I'd be willing.

So if a worker's hours get cut by 50%, they still get paid 80-83.5% of their wage. The company can choose to get the employees' pay back to 100% if they pay the difference, which sometimes happens if the hours are cut because there is not enough work and not because the company is in financial distress.
This helped quite a lot of companies to stay in business during COVID.
I admit that it's been heavily misused during Corona though, as every large corporation wanted to legally steal a little money from the state.
