It's definitely worth asking about.

I would speak to your manager regardless. They will know better than a bunch of random baristas on Reddit

I would call stores in the area that you are moving to and let them know that you are a barista/ssv/etc and that you’re interested in transferring there, but tell them you are available towards October. We had an ssv do that at my store and we just took his info and our SM worked with him to see if she could let him come to our store or reached out to other SMs in the district to see if they also needed an ssv
