Sacrifice the weakest barista to establish dominance

Sometimes it’s hard for baristas to adjust to one of the people they felt were their equal to now have a somewhat position of authority over them. You’re doing the right work and to have a SSV who holds baristas accountable to standards by coaching side by side is a huge asset for any SM.

That being said I will say while the power of delegation is now yours; do the dirty work in front of them sometimes. Run the trash, clean drains, do floors, clean bathrooms in front of them. Stand up for them if a customer is getting an attitude. Don’t jump right in to coaching all the time. Let things slide for now. Be their friend, many baristas have an issue with corporate and therefore leadership. Show them you are still one of them and on their side. Gain that trust as an SSV and give it time before you start coaching adamantly. Talk to your manager for support, you need all SSVs in your store enforcing the same level of standards. If the others are not you will get push back but you are in the right mindset. Establish trust, then start talking about standards.

When you coach on standards always explain why. Sanitize wand because if you don’t the wand acts as a vacuum and sucks up dried out milk and damages machines, etc. but give it time. You have a lot of new things to learn on your plate. Get established in your routine with opening/closing, pulls, counts, play calling, and leading a shift with positive mentality, encourage fun. Then start coaching. Good luck.

I’m kidding lol. Maybe ask the other SSVs for their input? That’s a shitty situation to be in dude I’m sorry :(

Make sure you're using the right commination style/tone of voice for each barista. I know it takes time to learn each person's communication style but trust me it will go a long way in getting the results you want. For example if a SSV barks orders at me I tend to shut down and feel unappreciated. But I know other people who would prefer the orders barked at them so they have a clear and concise instruction.

100% agree with @notcreative- . One of the ways I got trained and made my transition from barista to supervisor easier was leading by example. Even now, I will not ask any of my baristas to do a task I wouldn’t or haven’t done myself and they respect me for that. I’ve coached others by having them shadow me so they can see how to do a task done correctly in terms of Starbucks standard. Definitely take your time coaching and don’t jump the gun to correct just yet as you are also still learning; it took me over a month to feel comfortable in my position as the one responsible for the shift and my baristas, and believe it or not the baristas will notice that confidence too. Believe in yourself and your skills as a leader and don’t let anyone crush your confidence, you got this!

I had the similar experience for when I promoted to early into my hiring date (partner for 10months but a SSV for 7 of the 10 months), and I used to get this all the time from my friends and partners who were older than me.

What I did was I voiced my opinion, I said that even though I’m an SSV im a friend first, I wasn’t gonna go power hungry on them but I was gonna be just as a shift should be, a leader for the baristas. I basically broke that wall of “oh he’s different now that he’s a SSV,” and with enough of proving to them that you’re a good leader, they’ll respect you:)
I hope this helps😁

Don’t have any advice yet, but I’m 2 weeks into being an SSV too! Quite the change lol

You just need to be firm. If they don't follow routine, or are snotty about it, change the play. Some one leaves rags out on the counter after I told them not to, they go on POS. If they still aren't responsive take them BOH and explain to them why it's important to do things right. If they still keep doing things wrong then it's time to ask your SM to intervene.
