Publish the rota with a confirmation deadline. Operators tap confirm or 'can't make it' on their phone. By the evening before, you see who's coming and who hasn't responded. Three hours to find cover instead of three minutes.
A no-show stops the line
One operator missing on the 6 AM shift means the line starts forty minutes late. By the time you've called around to find a qualified replacement, you've already lost the morning's quota — and the late-comer's overtime is on Friday's payroll.
