In 2014, Belgian dismissal law experienced a real upheaval with the introduction of the so-called Single Employment Status Act. Whereas before, a distinction was made between blue-collar and white-collar workers for the calculation of notice periods, and in practice the notice period for the so-called senior white-collar workers (with a gross annual salary exceeding 32,254 EUR) was based on the so-called "Claeys formula", this became a thing of the past as of 2014. Indeed, the new law not only abolished the distinction between the two categories of employees (for notice periods anyway), but also imposed uniform rules on the calculation of notice periods. It therefore seemed that the Claeys formula could be buried for good.
