The illustrious history of machinists union belt buckles.
[P]olice sprayed pepper gas on some 800 [striking IAM workers] at the company's North Kingston plant in early 1982. Three weeks later, a machinist narrowly escaped serious injury when a shot fired into the picket line hit his belt buckle. The National Labor Relations Board subsequently charged Brown & Sharpe with regressive bargaining, and of entering into negotiations with the express purpose of not reaching an agreement with the union.
