The schedule checks these rules on every change, on the device, and again on the server when you publish. Warnings can be overridden with a reason; blocking issues cannot.

## Blocking rules

| Rule                                        | Trigger                                                                          | Fix                                                                           |
| ------------------------------------------- | -------------------------------------------------------------------------------- | ----------------------------------------------------------------------------- |
| Expired foreign-worker permit               | The person's permit expiry is before the shift date                              | Record the renewed permit under **Team › Compliance**, or roster someone else |
| Missing or expired food-handler certificate | A food-contact station and no valid food-handler training or anti-typhoid record | Record the certificate under **Team › Training & certs**                      |
| Blocked certification gap                   | The station requires a certification the person lacks                            | Assign training or roster someone qualified                                   |

## Warning rules

| Rule                        | Trigger                                                                            |

| Insufficient rest           | Less than the required rest between the end of one shift and the start of the next |
| Leave overlap               | The person has approved leave on that day                                          |
| Cross-outlet float          | The person is rostered at an outlet other than their home outlet                   |
| Expired typhoid certificate | The anti-typhoid record has lapsed                                                 |

## Overriding a warning

Open the cell, choose **Override**, type the reason, and tick **Employee agreed**. The override is stored with the shift and shown on the published roster.

## Coverage and cost

Under each day the roster shows coverage against the minimum staffing you set and, with analytics access, scheduled labour cost against same-day sales. Labour above 32% of sales is shown in red. These are informational, not blocking.

## Scope

These rules reflect the Employment Act 1955 as amended in 2022 for Peninsular Malaysia and Labuan. Sabah and Sarawak differ; outlets there see a banner rather than a wrong number. The rules help you comply; they do not replace your HR adviser.
