justasinger -- "What are the pro’s/cons to the two different types of sub?"
-- You should know about the RCA position by now, so here's the ARC side.
a. Assistant Rural Carrier ( ARC ) is not really a sub.
b. ARC's may only perform Saturday, Sunday, and holiday duties and will be paid on an hourly basis using the rate of pay in Table Four, the same rate as RCA's hired on or after 11 AUG 2012.
c. ARC's will be bargaining unit employees with limited contractual benefits. The may be union members.
d. Articles 15 and 16 will apply. ARC's will not have access to non-career employee health benefits, earned leave, or bidding rights.
e. ARC's are always paid actual time.
f. ARC's don't have a hiring exam, but all other hiring requirements will apply.
g. The ARC probationary period will be 90 work-days or one year.
h. ARC's have to apply for any desired RCA positions and may not automatically convert to an RCA vacancy.
i. ARC's may be required to proved a vehicle for delivery and will receive EMA.
j. ARC's will be entitled to Sunday and Holiday parcel delivery prior to RCA's.
l. ARC's may also case and carry routes on Saturday only after all available RCA's have been assigned and prior to working a regular rural carrier on the relief day.
m. The ARC will not be designated as the primary leave replacement on any regular routes and will not be included in any formula implementation or calculation.
n. ARC's may not work on Monday through Friday, except on holidays.
Not the rosiest of jobs, but may be good for someone with a set M-F schedule looking for some extra money.
While some regular carriers might want to trade with you, it's not possible. Regular carriers can do a mutual swap but in all likelihood will not get the route each other had as the route will go up for bids and the incoming regular will get the route that is open.
Once you decide on a southern location, get on the phone to the post offices in that area to check if for RCA vacancies.
Good luck.
