Yes, there may be options, but since you already work there, it wouldn't really be applying. I am going to guess that you have previous sbux/coffee experience. We are always happy to see this, of course. You owe it to your TL to be honest, and tell her it's not working for you. She probably knows it's bad already. I would support you moving departments if there is a place--not all stores would. If I were your TL, depending on the Barista situation, I would ask you to commit to working as much as a month more in sbux, so I could get someone else hired. I would at least expect you to finish the posted schedule. Advice to you on this last point, if TL is vague about time, insist on a date so it doesn't end up turning into 6 months.
If there are positions to fill, it seems likely that you will be able to change departments. HR will be able to help you.
