Can I refuse working at another office?

I’m an RCA well out of my 90 days. Lately my office had been sending me to another smaller office about an hour away from where I live. Every time they send me they tell me they’ll have the mail cased for me and a package runner for my parcels. This has been true 1 time out of the about 10 times I’ve been sent there, Leaving me on a route and a town I’m completely unfamiliar with. Not to mention this town has no Amazon help. Am I able to refuse going without risking my job? If it’s not my home office and I required to work there if scheduled?

Update: 3:00pm and not even halfway done w this route. If any carriers are in rural Wisconsin you’re more than welcome to come kill me.
