Outstanding annual leave – definition and causes
Outstanding annual leave is a term that every employee and employer should know and understand. Under the provisions of the Polish Labour Code, it refers to unused leave from the previous calendar year, which should be used no later than 30 September of the following calendar year. Failure to grant annual leave by this deadline can lead to various consequences for both the employer and the employee.
Why does leave become outstanding?
The main reasons why leave may become outstanding are often intense periods of work, during which the employer has the right to send the employee on outstanding leave at a later date. Other reasons may include the employee's state of health or the specific nature of the position, which makes it impossible to interrupt work. Sometimes negligence in leave planning can also contribute to a backlog building up.
Labour Code regulations
Under Article 168 of the Polish Labour Code, the employer is obliged to grant the employee outstanding annual leave. This is not only the employee's right but also the employer's duty, as they must ensure that the annual leave the employee is entitled to is used. This is important both for the employee's health and wellbeing and for the proper functioning of the organisation. Failure to grant leave by the 30 September deadline results not only in the employee losing the right to rest, but may also lead to the need to pay a cash equivalent for unused leave.
It is worth remembering that under the provisions of the Labour Code, every employee is entitled to paid annual leave, the amount of which depends on their length of service. Typically an employee is entitled to 20 or 26 days of annual leave, which must be granted to the employee no later than 30 September of the following calendar year.
Deadlines for using outstanding leave – the need to act by the end of September
Managing leave is one of the key elements of effective human resources administration. Under the Labour Code, there are clear deadlines specifying when outstanding annual leave must be used. Both the employees concerned and the employers responsible for granting this leave should be well versed in these deadlines to avoid potential misunderstandings or breaches of labour law.

The statutory deadline for using outstanding leave
The regulations clearly state that outstanding annual leave must be used by the end of September of the year following the year in which the days off were granted. For example, if an employee did not use their leave for 2022, they must use it no later than 30 September 2023. This requirement applies both to standard annual leave and to special forms of leave, such as maternity leave, if they are outstanding.
Consequences of not using leave on time
Failure to grant outstanding annual leave by the end of September of the following calendar year can lead to the loss of the right to those days off. The Labour Code stipulates that in such a case the leave lapses, which means the employee loses the opportunity to use those days for rest, and the employer avoids the obligation to pay an equivalent for unused leave. This is a way of obliging both employees and employers to comply with labour law and to promote a healthy balance between work and rest.
If the employer does not grant the employee leave by the set deadline, the employee has the right to pursue claims. In turn, an employer who fails to ensure that leave is used by the end of September may be subject to an inspection by the National Labour Inspectorate (Państwowa Inspekcja Pracy), which has the power to impose penalties for non-compliance with the regulations.
Both employees and employers should remember that outstanding annual leave must be used by 30 September of the following calendar year. This is not only a legal obligation but also an important ethical element, aimed at ensuring that every employee can enjoy well-earned rest, which contributes to better wellbeing and effectiveness at work. Failure to grant leave by the set deadline may result in serious legal and financial consequences for the employer.
Cash equivalent for unused annual leave
One of the most important aspects that should be well understood by both employees and employers is the right to receive a cash equivalent for unused annual leave. If an employee does not use the leave they are entitled to within the deadline set by labour law, they may claim a cash equivalent. The Labour Code regulates this issue in a way that protects employee rights.
The right to the equivalent
Under the Labour Code, every employee who ends their employment relationship without using all the days of leave they are entitled to has the right to an equivalent for unused annual leave. This applies to all cases of termination of an employment contract, regardless of who initiated the termination of the employment relationship. The employer is obliged to pay a cash equivalent for every unused day of leave.
Calculating the equivalent
The equivalent for unused annual leave is calculated on the basis of the employee's average remuneration. This value is obtained by multiplying the number of days of unused leave by the daily rate of pay, derived from the most recently received remuneration. It is crucial that the employer precisely tracks the number of days of annual leave the employee has left to use, in order to avoid unnecessary disputes and claims arising from the employment relationship.
Practical application
In practice, this rule may apply in situations where an employee's employment ends before they have used the annual leave they are entitled to for a given year, or when the employer is unable to grant leave on time. The employer may send the employee on outstanding leave, and if that is not possible, the cash equivalent must be paid to them.
Practical management of annual leave entitlement for the employer and the employee
Managing annual leave is a key element of the functioning of any organisation, affecting employee wellbeing and the company's operational effectiveness. Proper planning and use of leave helps avoid situations where an employee is left with outstanding leave, which can create complications for both the employee and the employer.
Leave planning strategies
Effective leave management requires thoughtful planning that covers all employees in the organisation. The key here is scheduling leave in a way that maintains continuity of work while respecting the annual leave rights employees are entitled to. Employers should strive to ensure that every employee uses their entitled days of leave, especially those from the previous calendar year, no later than the end of September of the year following the year for which the leave is due.
Planning should also take into account the specific needs of individual departments or employee groups, where the opportunity to use leave may be limited due to the nature of the work. In such cases, the employer can use human resources management tools that help spread days off evenly throughout the year, to avoid an accumulation of leave not used within the set deadline.
Tools supporting leave management
Modern technologies offer a range of solutions that can significantly facilitate leave management. HR systems not only serve to keep records of days off, but can also automatically remind about the approaching deadline for using outstanding leave. In addition, some systems offer analytical features that help identify leave patterns and can suggest optimal periods for scheduling days off, minimising the risk of disrupting the normal functioning of the company.
Introducing leave management systems, integrated with other human resources management systems, enables smooth and transparent management of annual leave entitlements. Employers can easily monitor how many days of leave each employee is entitled to, and employees have direct access to information about their remaining days off, which increases their satisfaction and motivation to work.
Summary
Meeting the deadlines for using outstanding annual leave is crucial for both employees and employers. Under the Labour Code, every employee is obliged to use outstanding annual leave for a given year no later than 30 September of the following calendar year. Failure to grant leave by the set deadline may result in it lapsing, as well as in the employer being obliged to pay a cash equivalent for unused time off. Adequate management of leave within the employment relationship not only protects the employee's right to rest, but also supports the effective functioning of the organisation. It is therefore crucial that both employees and employers are well informed about the applicable rules, which will enable effective planning and use of annual leave days on time.
