A time tracking system does not just store hours: it stores evidence. That is why security is not 'an extra'; it is part of compliance. Correctly defining roles and permissions reduces errors, prevents manipulation, and protects personal data.
1) Principle of least privilege: less access, less risk
Give each role only what it needs. The employee needs to view their record and request incidents. The supervisor needs to approve and view their team. HR needs to audit and export. Giving global access 'for convenience' usually ends badly.
Example: if any manager can edit clock-ins from any location, the system loses control. In multi-site environments, separating by location or unit reduces risks and improves accountability.
2) Segregation of functions: the person who works should not 'fix' their own data
Segregation avoids conflicts of interest. The employee requests; someone different approves. And if there is an exceptional change (for example, a mass adjustment due to a terminal failure), it must be recorded as an administrative action with a reason.
Example: allowing a supervisor to edit without a reason can create suspicion. On the other hand, approving corrections with a history and reason maintains flexibility without losing integrity.
3) Access by team and location: organise the operation
Define structures: locations, departments, teams. Permissions must follow that structure. That way, each manager views and manages their own area, and HR maintains a global view.
Example: in a chain, each store manager approves incidents for their team, but cannot access records from other stores. HR can compare metrics between stores.
4) Audit logs: the 'trail' that protects you
Any relevant action must leave a trail: approvals, corrections, shift changes. The log is not for surveillance; it is to be able to explain what happened in the event of an inspection or a claim.
Example: if a clock-in was corrected, being able to answer 'who, when, and why' reduces disputes and provides a defence in audits.
5) Win-win: trust and less manual work
For the company, well-defined roles reduce risk and prevent the system from becoming 'a spreadsheet with a password'. For the employee, it increases trust because the rules are the same for everyone.
When permissions and traceability are well designed, time tracking stops being a point of friction and becomes a stable and secure process.
