FYI:
I worked at a base that only had a call volume in 2006 of 217 calls.
Another base in the same service had a call volume of 120 for the year.
Another base had a call volume of 80 for the year.
The absolute BUSIEST base in the entire service of 14 bases in the service had a call volume of 701 in 2006 and it was near double the next busiest base.
ALL of the bases, from the 80/year to the 701/year had fully paid crews at them. By the way, our wage as a PT employee was $27.16/hr plus 14% in lieu of benefits.
Care to continue saying it is not possible to have a paid staff at all times?
