My dept had both Auxilliary (Unarmed, but wore same uniform, radio, light, cuffs, oc, unpaid) AND Reserve (Armed, same uniform, unpaid, indistinguishible from paid LEOs).
Auxlliary did mostly parades, went to community events, etc. Reserves were required to ride with a Full-Time member, or be partnered with one during any special events. Our city had very specific requirements for festivals, etc..where in Full-Time, PAID LEOs were required to be present in order to get the permit. Event organizer was to pay Dept ofcs Std OT rate + 15%. Dept would then pay officer the OT rate. If not enough full-time ofcs were availible to meet the staffing requirements, then Reserve Ofcs could apply for the detail and recieve pay.
The only other instance in which Reserve Ofcs could be paid was if they worked 20+ hours in a week due to crisis/emergency and there were not enough full-time ofc to cover shifts and crisis needs.
Yes, we were a unionized dept.
The Auxilliaries were more trouble than they were worth. Never failed that as soon as you called for 10-33, one idiot Aux would get on the main channel and ask to run a 28 in order to write a parking ticket.
Reserve guys were pretty good all around. Most just making time trying to get on full time with us. They had to go to our full-time academy and attend all dept training cycles.
