Staffing agency issues

IDAHO

1.Staffing agency threatened to fire me because I discussed wage increase and possible hire on with the company they sent me to for a temp to hire position, I believe that violates the National Labor Relations Act section about protected workplace discussion.

2. After a tense discussion with the staffing agency, I returned to work as normal but my next and most recent paycheck is now 96 hours late and they have stopped responding to me when I request updates on resolving the pay situation: Does this qualify as retaliation for the previous issue?
