The greatest success of the NLRB is....
Since this garbage was passed under FDR, Unions have declined in popularity with each decade. The Majority of states are now RIGHT TO WORK STATES which bar UNIONs from controlling employment.
Let it be known that FDR opposed all Government Unionization. The Union's claim to oppose greedy business owners is missing when they oppose Taxpayers who are not greedy business owners, they are the bill footers of government. Look where you have your Gov unions... Longshoreman, The US POSTAL SERVICE, American Public Schools. And in each instance, the Government service operates with no efficiency. Most prominent are the declining Maths and Science scores of Murican Students which coincide government-mandated education.
And the Longshoreman who have 100 ships backed up all year long and worse at Christmas, have a long history of opposing all automation. Shanghai which is fully automated and has no Unions, moves 500% more cargo a year than Long Beach and Port of LA combined.
