Why Time Tracking for Mobile Employees Matters So Much in 2025

Since the landmark ECJ ruling of 2019 and the subsequent national implementing legislation, one thing is clear: employers are obliged to record their employees' working hours in full and in a traceable manner – even when those employees work from a home office, on construction sites, in care settings or at customer locations. There is no exemption for "location-flexible working".

Yet this is precisely where many businesses run into trouble: traditional time-tracking systems – clocking machines at the entrance, Excel spreadsheets on office computers, paper timesheets – fail completely the moment the workplace becomes mobile.

Under the Austrian Working Time Act (AZG), records of the start, end and duration of daily working time must be kept for every employee – regardless of their place of work. Violations can be punished with administrative fines of up to €2,180 per employee.

The 5 Most Common Work Situations Outside the Office

Not every mobile employee is the same. Depending on the industry, different requirements arise for digital time tracking:

  • Home office: Fixed working hours, but no access to the company clocking machine – browser or app solutions are ideal.
  • Field service/sales: Changing locations, customer appointments – GPS time tracking and project booking are essential.
  • Construction/trades: Often poor connectivity, physical work – robust apps with offline functionality and a simple interface are necessary.
  • Care & social services: Shift work, multiple deployment locations per day – automatic shift detection and break recording are important.
  • Logistics/transport: On the road in a vehicle – time tracking must work without smartphone interaction (e.g. QR code at the depot).

What a Good Solution for Mobile Employees Must Be Able to Do

1. Multiple Recording Methods

Not every employee always has a smartphone to hand. The best software offers multiple ways to clock in: app, browser, QR-code scan or even phone dial-in – depending on the situation and industry.

2. Project Time Tracking

Anyone working for different clients or projects needs more than just a start and stop. Working time should be assignable directly to a project, order or client – for accurate billing and transparent post-calculation.

3. Automatic Break Rules

The Working Time Act stipulates a break of at least 30 minutes for working hours exceeding 6 hours. Good apps send automatic reminders, correctly book mandatory breaks and warn when maximum working hours are about to be exceeded.

4. Overtime and Balance Management

The hours balance should be transparent to employees and managers at all times – as a basis for time off in lieu, remuneration and resource planning.

5. GDPR-Compliant GPS Use

GPS tracking is a powerful tool – but only when used in compliance with the GDPR. Good solutions track exclusively during recorded working hours and store data on European servers.

GDPR note: If your time-tracking solution processes GPS data or location information, a Data Protection Impact Assessment in accordance with Art. 35 GDPR is recommended. Employees must be informed transparently about the nature and scope of data collection. In companies subject to co-determination, a works agreement under the ArbVG is required.

Conclusion: Mobile Time Tracking Is Not a Luxury – It Is Both an Obligation and an Opportunity

The world of work has changed. Anyone who believes time tracking is purely an office matter not only risks fines and legal disputes, but also loses sight of productivity and workforce planning.

Modern solutions for mobile time tracking are affordable, intuitive to use and can be rolled out within a few days. Whether you have five tradespeople or 200 care workers – there is the right system for every company size and every industry.
