Through most of the 1970s, collective bargaining was an accepted staple of American labor policy in the GOP platforms. The 1972 party platform included the line "demands responsibility in free collective bargaining, not only by labor and management, but also by those in government concerned with these sensitive relationships." The 1976 platform was the last time before Reagan's strong language was used, with "free collective bargaining remains the best way to insure that American workers receive a fair price for their labors."
With Reagan the candidate in 1980, the party platform shifted to stressing that collective bargaining be "consistent with state laws." It was no longer a national norm. Reagan decertified PATCO in 1981 and in 1984, collective bargaining as "sometimes" available and restricted to states laws.
Reagan fundamentally altered the labor policy of the GOP and portrayed an image of toughness for the private over the public sector that Republicans trying to reach national prominence have sought to replicate. In the 2008 GOP party platform, the party gives equal weight to the idea of Right-to-Work as well as collective bargaining but clarifies labor organizations "should be modernized."
