Simple shift schedule for 3 employees
Three employees means every hole is visible immediately.

Spreadsheets built for fifty seats feel heavy when you run Tuesday with Sam, Nour, and Lina. Enterprise tools want you to invite everyone as users. Your baristas want to know if they close Friday.
With three people, one sick call can erase a whole shift band. You need a grid that shows holes in amber before publish — not after the lunch rush.
Add three names. Set PINs for the counter. Assign Open, Mid, Close for the week. Publish once. Paste the message. Done.
When you grow past fifteen, you will outgrow BuOnly. Until then, the tool should be as small as your team.
