What is the average salary of unionized worker in the US?

Question

I'm just curious to know what the average salary is for the unionized worker of the lowest position at some place like a supermarket. I know that the majority of people I know who works in a supermarket without a union earns something from the minimum wage to under 10/hr, often without benefits.

Answer 1

There are not many unionized workers *left* in the US.

But the UAW website shows union people getting 20-30% more.  If a supermarket worker were getting $6.00 per hour, then presumably a *union* supermarket worker (not at Wal-Mart) would get about $9.
