Private vs. Public Sector: What Are the Differences?

The Private Sector

The private sector includes all businesses and organizations that are not managed or controlled by public authorities. While commercial companies naturally come to mind, it is important to note that non-profit organizations (ASBL) are also part of this category. The private sector employs the majority of Belgium's active workforce, commonly referred to as employees.

The Public Sector

The public sector comprises all public services, public institutions, and the education sector. Given that multiple authorities and official bodies are based in the Brussels Region, this sector offers numerous job opportunities in the city. Overall, the public sector employs about 10% of the active workforce.

In public service, you can work either as a "contractual" or a "statutory" employee:

• Contractual employees have a status similar to private sector employees: they are hired through an employment contract, either for a fixed or indefinite duration.
• Statutory employees are selected through official recruitment processes (such as Selor exams) and are formally appointed. Their employment relationship is not governed by a labor contract but by regulatory provisions established by the authorities.
• Statutory employees are known as civil servants and benefit from a distinct social security system.

An Example of Public Sector Management: The Buildings Authority

The Régie des Bâtiments (Buildings Authority) manages several real estate projects directly linked to the federal government. It serves federal institutions and has multiple responsibilities, including preserving Belgium's architectural and historical heritage. Additionally, the Buildings Authority fulfills Belgium’s infrastructure commitments towards international institutions, such as the Council of the European Union.

The Status of a Self-Employed Worker

A self-employed worker is someone who carries out a professional activity without being employed under a work contract (as in the private sector) or a statutory position (as in the public sector). A self-employed worker can be compared to a one-person business, responsible for managing their own social security (through a chosen social secretariat) and financial affairs.

Main vs. Secondary Self-Employment

A self-employed worker can operate:

• As their main activity, if their self-employed work is their sole professional activity.
• As a secondary activity, if they also hold a salaried job.

This distinction affects social security contributions and benefits accordingly. Many professions can be practiced under self-employed status, including lawyer, photographer, merchant, real estate agent, architect, doctor, notary, restaurateur, physiotherapist, and more.

Temporary Employment (Interim Work)

Many companies rely on temporary workers. They often use employment agencies that recruit and hire temporary workers on their behalf. Temporary job offers span across multiple industries, including hospitality (HoReCa), industry, administration, and event planning.

Why do job seekers register with temporary work agencies?

• Many young people gain their first work experience through temporary jobs, which strengthens their position in the labor market.
• Temporary work allows job seekers to explore new industries and careers, helping them to redirect their professional path.
• Some individuals are drawn to the flexibility and variety that temporary work offers.

Temporary work also requires an employment contract: the temporary worker signs a contract for a specific assignment with the employment agency, which then "lends" the worker to the hiring company. In principle, temporary workers receive the same working conditions (salary, pension, vacation, health insurance, etc.) as their colleagues employed directly by the company.
