Working hours tracking in mechanical workshops: what the law requires and how to comply

Since May 2019, Royal Decree-law 8/2019 has required all companies in Spain to record daily working hours for every employee, including start and end times. This applies to any mechanical workshop with employees, regardless of size. Non-compliance can result in fines ranging from €626 to €6,250 per infringement.

What the working hours log must include

  • Start and end time for each employee, every day.
  • Records must be kept for a minimum of 4 years and be available to employees, their representatives and the Labour Inspection on request.
  • The log must be reliable — it cannot be altered retrospectively without leaving a trace. A spreadsheet anyone can freely edit may not be accepted as valid during an inspection.
  • Overtime worked must be reflected in the log and communicated to the employee monthly.

Why paper and spreadsheets may not be enough

The law does not specify a format but requires the log to be "organised and accessible." A paper signing book can be lost or damaged. A shared spreadsheet can be modified without leaving a trace. In an inspection, the Labour Authority may question the validity of a record that offers no integrity guarantees.

A digital system where each employee logs entry and exit with immutable timestamps, accessible at any time, offers far greater guarantees than any manual system.

How TallerOS solves this

In TallerOS (Premium plan), the time-tracking module lets each mechanic record their check-in and check-out from the dashboard, with an exact timestamp linked to their user account. Records are immutable once saved and the supervisor can view them in real time, export them for payroll management and have them ready for any inspection — all from the same platform used to manage jobs.

Frequently asked questions

Is time tracking mandatory for workshops with just one employee?

The obligation applies to employees on a contract. If the workshop only has the owner as self-employed with no staff, the requirement does not apply. As soon as there is one hired employee, daily time logging is mandatory.

Can mechanics clock in from their mobile phone?

Yes. TallerOS is a web application accessible from any device, so mechanics can clock in from their mobile without any additional hardware.

Is time tracking available on the Pro plan?

No. The time-tracking module is an exclusive feature of the Premium plan.

Can I export the time logs for payroll management?

Yes. Time logs can be exported from the dashboard for submission to your accountant or payroll system.
