There should be a training manual that each new employee gets when he hits his office after "academy".
There is one, as
@Wilco183 mentioned above. I have a copy of one because I had some issues with how two new RCAs showed up in my office, so I was provided with one. I had never seen one before, and I'm not sure if the academy trainers actually hand these out to participants because I was told to return this one to them because they're so scarce and expensive.
As rural carriers, we don't get compensated for training new RCAs, so I understand the pushback from some regulars who don't want to do it. Training is not an easy job, it's not a job everyone has the skill to perform, and most of us would rather just walk in, deliver our mail and go home.
I'm probably in the minority here, but I think the three days training is sufficient if it's done right. If it's not done right, no amount of days will help. After three days, an RCA should be able to perform the functions of the job. Will they beat evaluation? No, but some supervisors, who are used to carriers who have 20 years of experience on H routes expect them to do so. Will they make mistakes? Of course, and regular carriers shouldn't flip out because a piece of mail is misdelivered, or third class mail is curtailed for those first few weeks.
Three days of training will not make a new RCA able to beat their evaluation or be perfect. Only time and experience will do that. This job is not a difficult one, in that you don't need to know how to use complicated machinery or process new information each day. It's not terribly complex work that we do, but it can be physically demanding and working outside in all sorts of conditions can be a challenge, but no amount of training is going to impact either of those factors.
The problem with the training program is that new RCAs very often don't get the three days of training in their offices. They're hired, they do four days at the Academy, and then they're thrown onto a route, sink or swim. I'm pretty critical of the four days spent at the Academy--I don't think it's a worthwhile use of anyone's time, and it's very expensive, but the fact is, some RCAs would receive zero training if it weren't for the Academy.
