O Snap -- Congratulations -- one of the first ARC's to post here.
-- Assuming that you have taken a test for an RCA position as there supposedly is no opportunity to convert to RCA from the ARC ranks.
-- Might as well take the high road and keep both post master appraised of your plans.
-- To be on the safe side, ask questions at the first post office. If hired there, you are probably off the hiring rolls, so if you start working at the smaller post office, then resign, you may have to retest to get back on the hiring rolls. Anyone???
-- Otherwise you will have to complete the probationary period as an RCA ( 90 work days or 1 calendar year ) in the smaller post office before submitting a written request to transfer to another post office.
-- And to do that, there must be an RCA vacancy at the office you want to transfer to.
-- Since the probationary period is the same for ARC's as well as RCA's, don't know if you'd have another probationary period as an RCA. Can manglement waive the RCA probationary period? Anyone??
-- Your background -- what have you done as an ARC? Cased and carried a route? Just assisted with parcels? Or...
