How Much Notice Does An Employer Have To Give For A Schedule Change?

The intricacies of staff scheduling and its legal implications often come as a surprise to many employees and employers. Many people are unaware that the Employment Standards Act (“ESA“) does not contain provisions that prevent an employer from adjusting an employee’s work schedule. However, employees do have certain rights in this situation. In this article, we will explore the basics of staff scheduling and its connection to employment law.

Unraveling Staff Scheduling and Employment Law: Staff scheduling is an integral part of workforce management. However, it is crucial to recognize that the Employment Standards Act (“ESA“) does not contain specific provisions preventing employers from making adjustments to their employees’ work schedules. This legal framework highlights the significance of understanding the rights and responsibilities tied to staff scheduling.

Minimum Requirements in Staff Scheduling: The ESA, while not restricting schedule adjustments, sets daily and weekly limits for work hours. In most cases, employees can be required to work up to 8 hours in a regular workday and 48 hours in a workweek. It is important to note that employees can agree to exceed these limits through written agreements. Exceptions apply to certain jobs and industries, so it is essential to explore these exceptions and their implications on staff scheduling.

Additional Insights into Staff Scheduling: Beyond the core work hour limits, staff scheduling must ensure that employees have a designated time each day free from work obligations. Essential components of staff scheduling include eating breaks, which we previously discussed in a dedicated article, Are You Legally Entitled To Breaks At Work In Ontario? These breaks contribute to employee well-being and productivity, making them a crucial aspect of effective staff scheduling.

Employer’s Role in Staff Scheduling: Employers retain the authority to set regular working hours and adjust work schedules as needed. Employment agreements typically contain provisions that grant employers the flexibility to manage staff scheduling. However, understanding the terms of these agreements is essential for maintaining a balanced and fair staff scheduling system.

How Much Notice Does an Employer Have to Give for a Shift Change: Generally, there is no statutory provision that requires employers to provide notice of a shift change.  However, it is recommended at least 48 hours’ notice before making a change to an employee’s schedule, including a shift change.

In certain situations, an employer require shorter notice if the change is for reasons beyond their control, such as an unexpected situation or emergency. It is important for employers to communicate with employees and, whenever possible, provide reasonable notice for any changes to their schedules.

The “Three-Hour Rule” and Its Implications for Staff Scheduling: The ESA introduces the “three-hour rule,” stating that if an employee works a shift under 3 hours, they are entitled to a minimum of 3 hours of pay. This rule also applies to employees accustomed to longer shifts but who end up working less than 3 hours on a particular day, despite their availability. In such cases, employees will receive either their regular rate for three hours of work or the earnings for the time worked, along with wages equal to the regular rate for the remaining time. It is vital for employers and employees to grasp the impact of the “three-hour rule” on staff scheduling and compensation.

Exception to the “Three-Hour Rule”: Notably, the ESA provides an exception to the “three-hour rule.” This rule does not apply when employees are unable to work due to circumstances beyond their employer’s control, such as power failures, severe weather conditions, or unforeseeable events. Understanding the situations where this exception applies is key to navigating disruptions in staff scheduling effectively.

Constructive Dismissal and Employee Rights in Staff Scheduling: While employers generally have the flexibility to make adjustments to staff scheduling, significant changes should not occur without employee consent. Fundamental changes without consent may amount to a constructive dismissal. Constructive dismissal arises when changes are so substantial that they effectively terminate the employment relationship.

It is essential to recognize that employees bear the responsibility of demonstrating that constructive dismissal has occurred. If you believe you have experienced constructive dismissal due to staff scheduling changes, we strongly advise seeking legal advice promptly. Understanding the legal implications of constructive dismissal is crucial for both employees and employers to foster a fair and harmonious staff scheduling environment.


In the realm of staff scheduling and employment law, knowledge is power. A deep understanding of the legal framework that governs staff scheduling, the “three-hour rule,” and employee rights is essential for both employers and employees. Whether you are an employer aiming to optimize staff scheduling or an employee looking to safeguard your rights, staying well-informed about these regulations and exceptions is pivotal in creating a harmonious and efficient staff scheduling system.
