How does one write a good resignation letter? Should the reason for quitting be included?
I had recently started a job. The person responsible for training was on vacation so the main manager trained us for a couple hours, then handed us off to a random person (in the sense it wasn’t her job to train) for a bit more. I’ve been told by others we weren’t properly trained and I certainly feel I lack training.
Also I did not know before starting that this job was essentially on call and would receive little notice of the time and location to work at. I was never trained how to read the schedule (I know it sounds strange, but they have a very complicated way of communicating work times and locations). In my resignation letter I don’t want it to sound that I’m blaming the manager for not being trained. Should I give any reason and if so what should it be?
Obviously I’m not going to say “I quit because you didn’t train me” but should I include “sorry I missed a shift, I was never trained how to use the schedule”?
EDIT: this is a government subsidiary and I don't want to burn any bridges in case I want to work for the government again in the future.
