How to Legally Earn Extra Income in Poland If You Already Have a Full-Time Job

More than 60% of people living in Poland admit that, due to inflation, their current income is either insufficient or barely covers basic expenses. This issue is especially relevant for foreign workers. Taking on a side job in Poland has become a practical way to improve your financial situation without changing your main place of employment.

So how can you legally earn extra money in Poland? Additional income can take many forms: weekend jobs, evening shifts, or short-term projects. Side jobs in Poland are available both for students and for working professionals who need flexible options. Let’s look at how to earn extra money officially, which types of side jobs are the most popular, and how to combine them with your main job without burning out.

Legal Framework for Additional Income in Poland

Since April 2023, Polish labor law has explicitly prohibited employers from restricting employees from taking up additional employment with another company. You have the right to maintain employment or civil-law contracts with another employer without needing approval from your primary employer. The only exceptions involve non-compete agreements or special contractual provisions.

There is no legal obligation to inform your employer about having another job. Employers are not required to coordinate work schedules with one another and may not even know about each other’s existence. Ensuring compliance with working time regulations, mandatory rest hours, and days off is your personal responsibility.

To work legally, you must have a separate contract for each job. The type of contract does not matter — it may be an employment contract (umowa o pracę) or a mandate contract (umowa zlecenie). Foreign nationals must obtain a separate work authorization (such as an oświadczenie or zezwolenie) for each job, unless they are exempt from this requirement. The law does not limit the number of work permits you may hold.

However, you cannot take a second job if it could harm your primary employer — for example, by working for a direct competitor while having access to trade secrets. Income tax (PIT) must be paid on all earnings.

Popular Weekend and Evening Side Jobs

Poland’s labor market offers many opportunities for earning extra income during your free time.

Working as a taxi driver through platforms such as Uber, Bolt, or FreeNow can bring in up to 8,000 PLN per month in large cities. Flexible schedules allow you full control over your earnings, and you can often start within a single day.

Courier services like Glovo, Bolt Food, and Uber Eats offer delivery work using a car, scooter, or bicycle. Income depends on weather conditions and physical endurance, but working across multiple apps simultaneously can significantly increase earnings.

The HoReCa sector (Hotels, Restaurants, Cafés) constantly needs staff, especially in tourist cities. Bartenders typically earn between 5,400 and 6,500 PLN per month, while buffet waiters can earn from 4,500 to 6,800 PLN. Many employers also provide accommodation and meals.

Freelancing opens doors for professionals skilled in writing, design, programming, or foreign languages. Knowledge of Russian or Ukrainian can be a major advantage when working in social media management or content creation.

Seasonal agricultural work includes harvesting berries, fruits, and vegetables in summer and autumn. Although physically demanding, it can be well-paid and allows you to earn quickly over several weeks.

How to Combine a Full-Time Job with a Side Job Without Burning Out

Polish labor law sets clear boundaries for combining multiple jobs. The average workweek cannot exceed 40 hours, with an absolute maximum of 48 hours. You are entitled to at least 11 consecutive hours of daily rest and 35 hours of weekly rest. Overtime is limited to 150 hours per year.

Foreign nationals must obtain written consent from both employers when combining positions. Verbal agreements are not sufficient. At the same time, employers are not obligated to inform each other — coordinating schedules remains your responsibility.

Australian researchers have found that a safe limit for maintaining good health is 39 working hours per week. Exceeding this limit negatively affects both mental and physical well-being, as individuals have less time for proper nutrition and hygiene. Working more than 55 hours per week significantly reduces cognitive performance.

You cannot work irregular hours without proper rest — this violates Polish labor regulations. In each job, you are entitled to full employee rights: paid leave, sick leave, and days off. Ultimately, responsibility for complying with rest requirements lies with you.

Conclusion

Earning additional income in Poland is now a legal and accessible way to improve your financial situation. The law protects your right to take on a side job without needing consent from your primary employer. In practice, you have a wide range of opportunities available — from courier services to freelancing.

The key to success lies in respecting working time and rest regulations. Remember the 39-hour weekly limit to maintain your health and productivity.
