I recall they mostly did BLS calls. If the patient was a pediatric, not in or go to a PICU, and they weren't on a 5150, it was dispatched as ALS without equipment, lol. Stanford didn't want BLS to transport pediatric patients unless they were on a 5150 hold. This was the majority of the night crew calls.
I worked there for about 8 months I think (I left in March 2012). I recall only once that our ALS crew got pulled into 911, which was on New Years/New Years Eve.
I don't think I asked for specific details on what they got paid, but one guy was quitting his job as a Paramedic in the Sacramento area to work at ProTransport-1 because ProTransport-1 offered him a lot more he said. He was going to work out of the San Francisco station I believe. I never followed up on him particularly. I know the Paramedics in Santa Clara County said they got paid a lot less than what they were offered, and then when ProTransport-1 got unionized, the Paramedics were mostly left out of the pictures, or what I heard them complained about.
While working there, I saw Paramedics only do 12 hour shifts. I felt like they mostly sat on the couch and watched TV, usually ran those pediatric BLS calls, but it was a pretty slow and easy, they seemed happy to me even though they felt like things could be better.
