Trust-based work hours | Shift Schedule Models | Workforce Management

In Germany, trust-based working time refers to an arrangement where work is organized around tasks and outcomes rather than strict timekeeping. 

This concept builds on a foundation of trust between the employer and employee. Employees plan their work based on the most suitable time to complete their tasks (be it from home, at the office, or on the go), and the employer relies on them to meet their goals and deadlines. 

Greater flexibility to manage family responsibilities, commuting, or taking advantage of productive morning hours can feel liberating. However, it is still essential to comply with labor laws (such as rest periods and maximum working hours). Following the European Court of Justice’s ruling in 2019, time tracking has become increasingly significant, with some employers requiring documentation or clear agreements to ensure compliance. 

Trust-based working time exemplifies one type of flexible working arrangement. It shifts the focus from mere presence to results but requires clear agreements and adherence to legal frameworks. 

In the next section, we will explore broader work models and flexible arrangements. This will help you better understand when trust-based working time is beneficial, its advantages, and the protective measures needed. 

Working time models define when, for how long, and occasionally where work is performed. These models range from fixed full-time schedules to highly flexible arrangements, tailored to meet the operational needs of businesses, industry requirements, and varying employee life situations. 

The Working Hours Act sets strict limits: 

The daily working time is generally a maximum of eight hours (up to ten under certain conditions). There must be at least eleven hours of rest between two working days. Breaks are mandatory, and all working hours must be recorded, even under trust-based models. Collective bargaining agreements and company agreements can provide additional flexibility. 

An overview of the traditional models 

Flexitime
Employees can choose when to start and end their workday within a defined timeframe (e.g., 7 a.m. to 7 p.m.). A mandatory core period ensures availability for team collaboration and customer interaction. Overtime or deficits are recorded in time accounts. 

• Pros: Improved work-life balance.
• Cons: Requires more coordination and self-management. 

Trust-Based Working Hours
Eliminates fixed schedules, focusing on deliverables instead. Employees organize their day autonomously, but success depends on clear objectives and a trust-based culture. Time recording, however, remains legally mandated. 

• Risks: Limits between work and personal life may blur. 

Annualised Hours
Matches working hours to workload fluctuations across the year. This model smooths out peak demand periods and slows down. Long-term accounts even allow sabbaticals or a phased retirement. 

Functional Hours
Ensures that specific teams or units have coverage during designated hours. Employees take ownership of team scheduling within those parameters, often found in service or administrative settings. 

1. Four-Day Workweek: Employees either compress their full-time hours into four days, reduce overall hours with adjusted pay, or, as emerging trials suggest, maintain their pay alongside shortened hours. Pilot studies report increased motivation and productivity, though flexibility is key to its success. 
2. Job Sharing: A single role is split between two employees, ensuring uninterrupted task continuity, diverse perspectives, and expanded skills. However, effective communication is vital. 
3. Hybrid Work and Remote Work: With hybrid setups, employees often combine flexitime or trust-based work models. This approach demands clear expectations and trust-centered leadership to function effectively. 

* Low planning effort for employers, but requires a high level of employee responsibility and trust. 

These trends show that it’s not just about new ways of working, but above all about how companies can organize them in a meaningful and sustainable way. This is precisely where Guido Zander, a partner at SSZ Beratung and a recognized expert on working hours and workforce management, comes in and he refutes the call for simply longer workweeks. In his articles and books, he demonstrates that, for physically demanding jobs, longer hours often lead to higher rates of sick leave and a decline in productivity per hour. Rigid schedules also create downtime when the order volume fluctuates. 

His solution: Companies need a variety of models with varying degrees of flexibility, from which employees can choose depending on their stage of life. Flexibility must benefit both sides. Employees need the ability to influence their schedules through requests and shift swaps. The resulting complexity can only be managed with modern IT systems and WFM solutions. Outdated planning boards have had their day. 

Optimization results in fair, legally compliant schedules. A self-service app allows employees to submit requests and swap shifts. Time management and time recording are integrated, and legal and collective bargaining requirements are automatically verified. Forecasting functions help respond to fluctuating demand. 

How Workforce Management (WFM) Software Makes Trust-Based Working Time and Flexible Models Practical 

Modern workforce management software is essential for integrating trust-based working time and flexible models into daily operations. It simplifies complex processes, ensuring that legal requirements, individual schedules, and business needs work seamlessly together. 

Key Features and Benefits of Software: 

1. Support for All Models in One System 
   Whether dealing with fixed hours, flexitime, shifts, functional hours, annualized work-hour accounts, or true trust-based schedules, the software manages all models simultaneously. It automatically verifies and applies the relevant rules for each.

2. Discreet Time Tracking Without Over-Surveillance 
   Even under trust-based setups, legal timekeeping requirements persist. The software records working hours effortlessly through apps or automated entries. Employees maintain their freedom while the company ensures compliance with documentation requirements.

3. True Employee Empowerment 
   Through a self-service app, employees can share preferences, swap shifts, and manage their availability. This feature enables self-management in flexitime and trust-based models without disrupting staffing needs.

4. Intelligent Planning Over Manual Methods 
   Advanced forecasting and optimization tools account for real demand fluctuations. These capabilities produce fair, well-balanced schedules meeting both organizational requirements and individual employee preferences.

5. Transparency for Trust-Building 
   With full visibility into balances, overtime, and rules, employees and management alike benefit from reduced misunderstandings. Transparency is pivotal in making trust-based working time feasible in practice. 

Workforce management solutions such as plano WFM bring these advantages to life, allowing companies to transition from theoretical flexibility to legally sound, operational reality. 

Yes, rigid work models are rarely productivity boosters; instead, they often act as barriers. Such models increase fatigue, error rates, and long-term health risks. Properly designed flexible work arrangements, on the other hand, frequently result in higher performance, fewer absences, and happier employees. 

Research Insights: 

1. Impacts on Health: According to a 2021 joint report from the WHO and ILO, long working hours (exceeding 55 hours per week) significantly raise the risk of stroke and cardiovascular diseases.

2. Fatigue and Errors: Prolonged presence at work correlates with mounting exhaustion and higher error rates, ultimately diminishing hourly output.

3. The Role of Flexibility: Work-from-home arrangements and flexible work models have consistently demonstrated benefits in employee satisfaction and productivity. Provided they are governed by clear policies and trust-driven leadership practices. 

Key Implications for Businesses: 

• Focus on efficient work distribution rather than extended hours. Prioritize quality over quantity. 
• Trust-based scheduling can be highly effective, if legal compliance (such as time tracking and rest periods) is ensured. 
• Rigid shift schedules often exacerbate inefficiencies, causing downtime when demand is low and workforce strain during peak periods. Modern workforce management systems are essential to maintaining balance in these scenarios.
