The quality of management and your fellow partners have a big impact on the answers here. So it's hard to say if you've never worked at the store you'd be transferring to.

If your manager is good, trains you for your role and duties well, it's definitely worth the money. Frankly there are some tasks that pull you off of floor coverage that are a bit of respite from it, like dropping tills and doing pulls. If the baristas get along reasonably well and it's not constant interpersonal drama or everybody trying to get out of one necessary position, leading a team isn't hard once you get the hang of it.

If you go untrained but the manager still holds you to all the high expectations, that sucks for obvious reasons. If you're trained but the baristas at that store are jerks, being transferred in as a new shift without established relationships to draw on when coaching can be hard.

So my advice would be to meet the manager, work a shift or two as a borrowed partner there during the right day part, and see how it feels. You'll get a good sense of the vibe pretty quickly.

The higher pay is good and all but I personally don’t think it’s worth the stress. I agree with the person above that you should definitely check in with that store’s manager. Because if that SM is bad/doesn’t care about your well-being they’re going to understaff
the majority of the time and leave you with a huge workload where you have to do barista stuff and have to rush your SSV stuff. All this while having to answer a million questions a day, coach, and run breaks etc. This is my situation atm and have been wanting to transfer away from my awful new SM and become a barista again at another store. The stress is literally eating me alive.

But if you think you can do it, go for it. Just try not to take things so seriously and take it one day at a time. And leave work at work. That’s all. I will say, the partners really make working here worthwhile. But from my personal experience, I thought the job was waaaay more enjoyable when I was a barista.

Lastly, I was also pushed into SSV 6 months into being with the company so I feel like I wasn’t totally prepared so you might be much better suited with 2.5 years up your sleeve).
