However, given that the government FORCES "good faith negotiations", all bets are off, kids.

Also, in regards to this:

First, the unions are free to set up non-exclusive agreements so that they only represent their members and not non-members.  But unions overwhelmingly refuse to set up this sort of agreement, choosing instead to coerce people who don't want to be in the union.

Not true. 29 USC 159 states that:

(a) Exclusive representatives; employees' adjustment of grievances directly with employer
Representatives designated or selected for the purposes of collective bargaining by the majority of the employees in a unit appropriate for such purposes, shall be the exclusive representatives of all the employees in such unit for the purposes of collective bargaining in respect to rates of pay, wages, hours of employment, or other conditions of employment: Provided, That any individual employee or a group of employees shall have the right at any time to present grievances to their employer and to have such grievances adjusted, without the intervention of the bargaining representative, as long as the adjustment is not inconsistent with the terms of a collective-bargaining contract or agreement then in effect: Provided further, That the bargaining representative has been given opportunity to be present at such adjustment.

Unfortunately, the government is the one saying "Ha ha! F you, workers!".
