Discover the impact on your salary, holiday pay, leave and pension, and take the step to a job as a technical employee.

Switching from blue-collar to white-collar means a different status: you get a fixed monthly salary, holiday pay is calculated differently, notice periods change and your leave entitlement is accrued in days instead of hours. You keep your seniority, but the tax burden may differ.
The transition mainly affects your pay slip and rights. Importantly, your seniority carries over, so accrued benefits are not lost. Your pension accrual also continues, but the amounts may differ. Read below what this means for you in concrete terms.
In Belgium, there was long a strict distinction between blue-collar and white-collar workers. Blue-collar workers mainly work with their hands in a manual role, while white-collar workers perform an intellectual or administrative task. Since the introduction of the unified status in 2014, many differences have been eliminated, but important nuances still exist in terms of salary calculation, holiday pay and dismissal rules. For technical employees, a role that often falls between the two statuses, it is extra relevant to know what the switch concretely means.
As a blue-collar worker, you typically receive an hourly wage, while a white-collar worker gets a fixed monthly salary. That means your income becomes more stable, independent of the number of hours worked per month. Overtime is regulated differently for white-collar workers: you often get compensatory rest instead of a supplement. Want to know what your salary looks like after the switch? Use our salary calculation tool for technical employees.
This is one of the biggest differences. Blue-collar workers receive their holiday pay through the National Annual Holiday Office (RJV), based on the salary of the year before last. White-collar workers receive their holiday pay directly from the employer, and it is calculated on the basis of the current salary. If you switch during the year, a mixed system arises: you are entitled to a part via RJV and a part via the employer. Read all about it in our guide on holiday pay when changing status.
Blue-collar workers accrue leave in hours, white-collar workers in days. In addition, white-collar workers are entitled to full pay during public holidays, while blue-collar workers depend on sectoral regulations. After the switch, you no longer count in hours, but in days. That makes planning easier, but note: the first holiday day after the switch may be treated differently for tax purposes.
White-collar workers generally enjoy longer notice periods than blue-collar workers, especially as your seniority increases. That offers more security in case of dismissal. The calculation of the severance pay also differs. If you are in doubt between the two statuses, you can consult our comparison table.
Pension accrual itself does not fundamentally change: both blue-collar and white-collar workers build up a statutory pension. The difference lies in the salary on which your pension is calculated. Because white-collar workers often have a higher gross salary, this can result in a slightly higher pension. In addition, there are sectoral supplementary pensions that may differ. For technical employees, it is often attractive to switch, because the role is well paid.
Yes, your seniority is retained when you switch from blue-collar to white-collar with the same employer. That means accrued benefits such as extra leave days or salary increases are not lost. Note: if you switch to a new employer, your seniority starts again, unless there are sectoral agreements.
There is no clear-cut answer to who pays more taxes. It depends on your total salary package, company car, meal vouchers and group insurance. White-collar workers more often receive fringe benefits, which can positively influence your net income. But a higher gross salary also means more social contributions and withholding tax. Simulate your situation via our net salary calculator.
The advantages: stable monthly salary, longer notice period, often better fringe benefits, and for technical employees more growth opportunities. Disadvantages: the transitional arrangement for holiday pay can be complex, you lose flexible working hours and in some sectors the collective agreement benefits for blue-collar workers are still interesting. Weigh carefully what matters most for your situation.
If you get the chance to work as a technical employee, it is often a smart career move. Not only do you usually earn more, you also build more security. Curious which vacancies are currently open? Check out our current list of jobs for technical employees in Flanders and apply today.
