Hello, I have left UPS about a month ago to prepare myself for joining the military. I've have gotten a verification from my union that it has been terminated until I rejoin another union job but today I've gotten a letter from the Pacific Coast Benefits Trust stating the account balance I have from them. Is this a trust fund or a 401k or a pension? I do not really understand how that works as I never encountered this working in other jobs part time while going to school. Is it possible to ask them to cash out and take a percentage lost, do I have to wait until I am at retirement age to even do that, or should I just leave the money in there and will it build or something? It would be nice to just have the extra money than let it sit unless there's a investment percentage in it.
