Your analysis is completely wrong and your quotes are completely irrelevant to disproving my point. Here are the facts:
1) FDR specifically stated that he was not for collective bargaining.
2) FDR specifically stated that government employee unions should not be able to negotiate wages through collective bargaining.
3) FDR specifically stated that government employee unions should not be able to negotiate working conditions through collective bargaining.
4) In relation to #2 & #3, FDR related his own experiences as Assistant Navy Secretary to illustrate those points.
5) The document you reference specifically delineates FDR's thoughts on collective bargaining and strikes. There is no implication that he equates collective bargaining to striking. He states he is opposed to the two.
6) The historians at his own library agree with me.
