In the year 1966, local 587 was in it's infancy. The charter was signed in November of the previous year and this was to be the first full year of the local's existence. George Silvia was the residing President with Harold Dennis sitting in the Chief Steward's chair. Filling the Shop Committee positions were J. J. Spotts, Jr., N. M. Violet, and G. H. Capron. The Vice President, who's position was not part of the negotiating committee at the time is not known at this point due to the lack of available documentation for 1966.

After serving as Local President, Chief Steward Harold Dennis left local 587 and Raytheon to start his own machine shop in the area.

The negotiating committee, along with Business Agent W.J. Baillargeon, met with the following company negotiators to forge this year’s contract:  Ralph Martin, Fred Darnley, E. Leonard Kane, W. Rogers Hamel, Robert Dewhurst, Robert Crump, Walter Lee
