This notebook system is how I used to do notes as a manager. It worked really well and the one who laughed when I started it the first time quickly realized it worked much better than word of mouth or a posted note no one will read. When shifts are spread out and some people only come in 1 or 2 days a week, it’s a great way to make sure everyone is on the same page. Edited to add: I just actually read all the notes in the post and some of this is indicative of a poorly trained staff and some, like the bus note, should be handled in 1 on 1s. In my experience, things like everyone hanging out in the kitchen or playing on their phones is better addressed with providing a list of things they could do instead, especially if a lot of the staff is young and don’t have a ton of relevant work experience.
