I'm a fairly new RCA, working since Dec 2017. I'm trying to get my head wrapped around how we are paid. I understand the basics of the evaluated time system and straight time for Amazon days. The ELM is a bit confusing and I didn't find any answers there.2nd Trips - In my post office, when the mail truck is late (fairly often) we will deliver packages to reduce the load. We will claim mileage for this. Would this be considered a 2nd trip? If not, how should 2nd trips be handled? I saw somewhere that 2nd trips should be paid on a green card. Where is this in writing?Overtime - I understand that if you exceed 40 hours evaluated time you are paid overtime for those hours over 40. I also understand that if you exceed 40 hours actual time you are paid for those hours in lieu of the evaluated time. For example your evaluated time for the week would be 45 hours but you actually worked 43 hours, you would receive the 43 hours. It seems silly, but that is how it was explained to me.12 Hour Work Day - If you exceed 12 hours in a work day, there is some sort of overtime paid, I think.Those are a few of my questions. Is there a document/manual/training session where I can learn about the USPS pay system? I'm not afraid of work but I want to ensure I'm being rightly paid.
