You raise valid points, and there's probably something to be fixed about this part of the bill. Personally, I considered unions more as a mean than as an aim for employee representation. FTR, this is not necessarily unworkable even in low-unionzed countries, as France has one of the lowest unionization rates in Europe. But still maybe that's not the best thing to do. Do you have any alternative suggestion of a system to ensure representation of the two components ?
Sorry, but I was taking time to look at how the original board for the SSA was set up. In order to keep with the intent of your bill's council, how about the following:
(1) Make the council 7 members all appointed by the President subject to Senate approval
(2) The council must have at least one member from each major party
(3) Two must be employees (with nominations for the President coming from the unions) two must be business (with nominations from business organizations) and the remaining three up to the President subject to the above limitations.
