From the National Association of Letter Carriers:
Nov. 9, 2013–Pursuant to the Memorandum of Understanding Re: Residual Vacancies–City Letter Carrier Craft (M-01824), the first wave of city carrier assistant (CCA) conversions to full-time career status took place Nov. 2.
While the exact number of conversions that took place on Nov. 2 has not yet been finalized, NALC estimates that somewhere between 1,500 and 2,000 CCAs, most of whom had served multiple years as transitional employees (TEs) prior to becoming CCAs, were converted to full-time career status to fill vacant full-time letter carrier jobs.
Those who served as former TEs directly before their CCA appointments will not serve a probationary period as full-time career letter carriers (see M-01826).
As vacancies continue to be filled through the steps in M-01824, more CCA conversions should take place in the coming weeks and months.
