What the supervisor does that a coordinator cannot
A coordinator can log an issue, arrange a return visit and update a record. What they cannot do is stand in the room and see that the marks on the wall are not dirt but scuffing from a trolley, that the amenity smells because a floor waste has dried out, or that the shift is running long because a delivery area is being cleaned that was never in the scope. Those judgements require a person on site.
They also require someone with the authority to change the arrangement. A supervisor who can move a task to a different night, reassign a cleaner, order a periodic treatment or escalate a building fault will resolve most issues in one step. Sending the same issue through three people, each of whom can only pass it on, is how a small matter becomes a monthly complaint. One person with authority resolves in a single step what three people resolve in three weeks.
