Five rostering mistakes that quietly destroy your margin

Mistake one: rostering to availability rather than demand. If your roster looks the same every week but your demand does not, you are paying for idle hours.

Mistake two: ignoring skills coverage. A shift that looks staffed but lacks a qualified lead will run slower and often needs rework.

Mistake three: publishing without a cost check. A roster is a purchase order for labour — approve it like one.

Mistake four: allowing informal swaps. If a change is not in the system, payroll will find out the expensive way.

Mistake five: no feedback loop. Compare rostered versus actual hours weekly and the pattern of overruns becomes obvious in a month.
