In Altamira’s time and attendance system, anomalies are automatic alerts that indicate situations not compliant with the assigned work schedule or company rules. These checks are based on the specific attendance model assigned to the employee, which defines the criteria the system uses to detect discrepancies.

When the recorded data does not match what is expected based on the configured rules, the system flags an anomaly.

Anomalies do not necessarily indicate a serious error, but they highlight a record that requires review or action. In many cases, they can be resolved with a justification or by correcting the clock-in/out entries.

Why anomalies appear

Anomalies appear when the system detects something that does not match the rules defined for the employee, such as an unplanned absence, a missing clock-in/out, or a time entry outside the permitted limits.

Their purpose is to support attendance control, helping you identify and address irregularities quickly.

Common examples of anomalies

• Missing clock-ins/outs (entry or exit)
• Clock-ins/outs outside the expected time slots or inconsistent with the assigned shift
• Unjustified absences
• Workday duration does not match the attendance model

Who can view and manage anomalies

Anomalies are visible to both employees and administrators:

• Employees only see their own anomalies and can take action by requesting changes or submitting justifications.
• Admins or HR have full visibility and can manage all employee anomalies, either by correcting them manually or by approving submitted requests.

What to do when an anomaly appears

It’s important not to ignore an anomaly, as it can affect the calculation of worked hours, leave, or vacation days. The first step is to review the anomaly details to understand its cause.

Depending on your role:

• If you are an employee: you can submit a missing clock-in/out request or justify the absence directly from the system. See also: Submit an absence request 
• If you are an Administrator/HR: you can approve the request or manually correct the anomaly. See also: Process attendance 

Goal of anomaly management

Proper anomaly management ensures that attendance records are consistent with the employee’s actual workdays. This helps prevent errors in monthly reports, overtime calculations, and payroll.
