Hire Employees in Poland From Belgium

Both countries protect employees well, so this is not a flexible versus rigid comparison. The gaps are in formalities, procedure and cost structure. In short, exiting an employee usually costs more in Belgium, while in Poland the main risk is getting the procedure wrong.

A written contract is expected from day one. Belgium allows a standard indefinite full-time contract to exist without a signed document. In Poland the contract should be in writing, and if it was not signed, its terms must be confirmed in writing before work starts, with further information on working conditions generally due within 7 days of the start date.

The contract language matters. Belgian employers already know that language rules can invalidate a document. Poland has its own version, the contract generally has to be in Polish where the employee lives and works in Poland. A bilingual version is allowed, and for Polish citizens the Polish text prevails if the two versions differ. For foreign nationals who do not understand Polish, the content must be provided in a language they understand, and the employer generally has to keep a sworn Polish translation. An English-only contract copied from a Belgian template is not a safe starting point.

Probation works differently. Belgium abolished the general trial period in 2014 and, for contracts starting from 1 August 2026, uses a uniform one-week notice period during the first six months instead. Poland has a dedicated probationary contract of up to 3 months, with its own short notice periods of 3 working days, 1 week or 2 weeks depending on duration.

Poland expects a stated reason. In Belgium the employer does not have to volunteer the reasons for dismissal, although eligible employees can ask for them. In Poland, a written notice of termination must state the reason, tell the employee of the right to appeal, and may require prior consultation with the trade union. A sound reason does not rescue a defective procedure.

Notice is shorter, and the exit risk sits elsewhere. For an employee with 8 years of service, Belgian notice is around 27 weeks, in Poland it is 3 months once the employee has at least three years of service. Belgium’s cost sits in the indemnity in lieu of notice, which includes benefits such as a company car. Poland’s sits in the procedure. Where the employer gets it wrong, a Polish court can order reinstatement or compensation, generally between 2 weeks’ and 3 months’ pay, and for protected employees reinstatement with pay for the whole period without work.

Statutory severance exists in Poland for some dismissals. For redundancies, and certain individual dismissals for reasons unrelated to the employee, Polish law requires severance of one month’s pay for service under 2 years, two months for 2 to 8 years and three months beyond 8 years, capped at 15 times the minimum wage. Belgium has no statutory severance on top of notice.

Some employees cannot be given notice at all. Poland blocks notice during annual leave and justified absence such as sick leave, and gives wider protection to pregnant employees, those on maternity or parental leave, employee representatives and employees within four years of retirement age. Check protection before any exit decision.

Non-competes are priced differently. Belgium requires compensation of at least 50% of salary, caps the restriction at 12 months and applies salary thresholds. Poland requires at least 25% of prior pay for the restricted period, applies only to employees with access to particularly important information, requires writing and sets no statutory maximum duration. A clause lifted from a Belgian contract will not transfer cleanly.

Pay is set differently. In Belgium the joint committee for the sector drives minimum salary scales, indexation and sector benefits. Poland has no equivalent sector layer determining the basics, pay follows statute plus the employer’s own and any sector rules. Polish employers also cannot ask candidates about their current or previous pay, but must tell candidates the starting salary or range early enough in the process.

Working time and internal rules. Poland’s standard is 40 hours a week on average, with alternative systems allowed and reference periods of up to 12 months where justified. Employers with 50 or more employees generally need work regulations. Neither can be copied from a foreign template.

New anti-mobbing rules arrive in November 2026. Poland’s reform redefines mobbing around persistent, repeated or continuous harassment, removes the separate long-term requirement, and sets minimum compensation of at least six times the minimum wage, PLN 28,836 in 2026. Employees who complain, and those who support them, are protected against retaliation including dismissal. Employers have six months to adapt their internal procedures. A dismissal already planned before a complaint is not automatically blocked, but it needs a genuine reason that stands apart from the complaint.

Pensions run on a different model. Poland’s mandatory ZUS pension applies to everyone, with retirement ages of 60 for women and 65 for men and no general early-retirement route based on long service alone. On top, PPK enrols employees automatically with a minimum 1.5% employer and 2% employee contribution, and employees can opt out. Belgium’s legal retirement age is 66 and rising to 67 from 2030. Belgium’s 80% tax rule on supplementary pensions has no Polish equivalent.
