Fivexer

Staff scheduling rules

Make the rule visible where the assignment happens.

A policy document cannot check Thursday’s replacement by itself. Configure the working rules that apply, keep the relevant worker records current and inspect warnings before approving the roster.

The short answer

Fivexer checks the working rules you configure — rest, rolling hours, qualifications, availability — against every assignment in the roster, and shows the arithmetic behind each warning before a planner publishes.

What it checks
Rest intervals, rolling hours, required qualifications, site permission and availability.
What it does not supply
Any country's legal limits as defaults. A blank rule is not checked; a configured rule is enforced and explained.
Who decides
Your planner. Fivexer explains the conflict and records it; it never publishes on its own.

Check the boundary of the week

Monday’s first shift can depend on Sunday’s last shift. Include relevant history when checking rest and rolling hours. A clean-looking week is not enough if the previous period has been omitted.

Keep required rules distinct from preferences

Availability, required qualifications and configured limits determine whether an assignment is allowed. Preferences help choose between eligible alternatives. Review which conditions are mandatory before assuming a generated plan reflects your working agreement.

Explain a warning before changing the setting

A warning may mean that the worker record is wrong, the shift is wrong or demand cannot be met. Check the underlying facts with the responsible planner. Changing a limit just to remove the warning changes the policy the system enforces.

What to account for

Fivexer ships no country’s legal limits as defaults. Rules vary by jurisdiction, sector, agreement and person. A blank rule is not checked; a configured rule is enforced and explained.
