Sorry this is so long!

Just to give some info, I have been with the company for 4.5 years. I was a shift manager in MA for a while before transferring to a different state as a Shift Supervisor. I am very aware of everyone around me and I do my best to word everything I say (or write in the book) carefully to ensure a comment doesn't seem aggressive. I know I make mistakes and I have no problem taking responsibility for them. I have worked tirelessly to ensure limited tension between each partner. I know it can be a difficult job, especially right now, and I just want every partner who continues with my store to know they are appreciated greatly. If a partner decides to leave, I tell them I will miss them but I understand the want/need to get out of this environment. (My current store also has a terrible reputation because we are high volume, and high incident which of course causes a high turnover)

So to get into this, I am an opener but I used to close more often. My store is on limited hours so we close at 4pm. I know how rough it can get to close so I do my best to get basically all the closing tasks done before my crew leaves. I generally do both pulls and start the counts as well so the closer can focus on breaks and really just has to finish the deposit and the count. However, one of the closers has recently been telling their baristas I am bullying this shift and keeping them out of the loop. I'm just kind of at a loss of what to do. Recently, they wrote in the book that we have a fifo problem because she had to throw out a lot of pastries. A couple days later I wrote that I agreed with them and that I found a couple full trays of food that had expired on the BOH pastry cart that had expired 3 days before. I also spoke to them about this and tried to make sure they understood it was not a personal attack as clearly, we had all missed it and I was glad they brought attention to this problem. Then I got messaged later that night from a closing barista saying this shift was complaining about my comment in the book saying I was bullying them and causing unnecessary tension. I do plan on talking to the shift to just understand what more I can do to make sure this confusion does not happen again. However, since I talk to them all the time and they never say anything, I don't expect it to do much. Is there anything else I can do other than just live with it? I want to talk to my SM as well but he basically refuses to talk about negative things to anyone in the store since we are so short staffed. I really love being a shift and being able to support my partners but lately it just seems like they're suffering more because of this tension. This has been going on a long time and more partners are changing their availability because of the negativity this shift brings to their closes, which of course makes closing that much more difficult. Its honestly all a mess and I just don't know what more to do. If anyone has advice I would really love to hear it.
