“businesses would face a labor shortage”
There always is a “labor shortage” for these people.
What it really is is a “pay shortage.”
If we “face” in the future a specific identifiable shortage, we can craft bills later.
The “business” do not like supply and demand, and fair bargaining.
They want the senators to juice their profits now and quickly.
When there is a shortage of product produced by farmers, oil companies, or any other business, their first move is to raise prices. However, when there is a shortage of labor, they seldom consider solving the problem by raising the price paid for that commodity. I fail to see how any business should be guaranteed an unlimited supply of cheap labor.
