If you are undertaking the management role of volunteers for the first time there are several factors you should understand. Not all volunteers do the same thing, are capable of doing the same thing, nor is it desirable they all do the same thing in communications. On one hand, you need people who do a repetitive function under close supervision. Others perform repetitive duties with little or no supervision. On the other hand you need (or should have) people who lead, solve problems, plan ahead in the short term, those who are good at long term planning and preparing standard operating procedures.
CA State OES began the Bulletins in the early 1950's to assist agencies and radio operators to become more familiar with RACES. They were issued periodically until 1985, at which time they began to be issued weekly over voice and digital radio systems of Amateur Radio and in print. Originally intended for California, increased demand, and a 1988 request by the ARRL for national distribution, led to their eventual worldwide distribution.
