The job involves what the government refers to as 25% availability pay.
Essentially, federal LEO’s on this have to work a regular 40 hour week, plus they have to be “available” to work another 25% or 10 hours a week. In exchange, they automatically get their salary upped by 25%
This is an average computed over a three-month period. You can easily, say, work 20 extra hours one week and zero the next.
My experience is that being “available” means working, not sitting around waiting for your pager to go off – though in theory this can count.
The Sky Marshall job is a bit unique in that scheduling work is dependant on airline flights, connections, etc. Also, I believe they will have some on-ground responsibilities.
Overall, it sounds like a miserable job, esp. as you get older. I really think a job with DEA, ATF, etc. would be a lot better.
After about 5 years on the job, they’ll probably be making about $70,000 - 80,000 a year, at a minimum.
