Rostering is often complex, so visual alerts and status indicators help warn or block any potential issues
When rostering, there are some standard rules that apply across the board - for example employees can usually only work one shift at a time, so shift clashes are something that Ento will automatically flag and warn of on a roster.
Other alerts may simply show that a staff has requested to drop or swap a shift. Other alerts can vary - where one business will want to be warned when overtime is triggered, another may want to put a block in place to prevent it entirely.
Another company may expect to pay overtime and not want it highlighted on the schedule at all. To support such varied business needs alerts can be customised, and alerts may even vary for employees from the same company on different awards.
Alerts
For any shift that is showing an alert, click on it and the information panel on the right side will advise why you're seeing an alert so that you can investigate and resolve it.
Colours
Red - critical alerts
Critical alerts are used for shift clashes, and can be set for compliance failure with major award rules. Examples could be trying to schedule employees after a hard set maximum number of hours per week, qualification non-compliance or the minimum time between a shift ending on one day and their start time the following day not being met.
Yellow - low Alerts
Often used as warnings, alerting those scheduling when they are about to perform an action that it would be better to avoid, for example where an overtime rate has been triggered, or where a rostered break is not long enough, but where rostering would still be allowed.
Warnings
When you try to add or change a shift that causes a warning, you will receive a small popup in the left hand corner of the roster advising there was an issue.
You can hit 'undo' to revert the action, or you can 'view details' to see an outline of the warning. When viewing the details you can opt to ignore the warning and make the change anyway if your permissions allow it.
Other alerts
Shift action required
A small bell icon on a shift is an alert to let you know that some action is required for a shift.
If your employee permission profiles are set to require shift acknowledgement, this bell will first appear if the employee still hasn't accepted their shift 24 hours after the schedule was published.
Alternatively, if an employee has requested a shift swap/cover/drop and it requires manager approval, this bell will appear to let you know.
Fill-ins
The head icon means represents a shift that has been offered out to employees so they can pick it up. If it's grey, there have been no replies, but if it's green then an_employee has advised they can work this shift and could be selected.
Pending shift swap/cover
Employee has requested to swap this shift with another employee, and it's waiting for them to approve.
Action cards
The information panel will display action cards where some form of approval is required. 
Depending on the request, it will display more or less information, and give you action buttons to approve, deny, or view more information as necessary.
Alerts and manager permissions
What a manager can do in instances of low or critical alerts when scheduling is controlled in each Manager permission profile. In some cases there may simply be a warning, in other instances the action may be blocked.
This allows for hierarchical overriding, so while a scheduling manager's permission may block them from creating a shift where a low alert is triggered, while an operations manager's profile may only give a warning when triggering a low alert, but still block for critical alerts.
Your Ento administrator will be able to access the Rostering tab of your Settings > Manager permissions profile to determine what attempting to roster low or critical alerts will do.
