The Unified Employment Status Act aligning the notice periods for blue- and white-collar workers obliges the sectors of industry to enter into a CBA, at the latest on 1 January 2019, reducing the notice period or indemnity in lieu of notice for workers that are entitled to a notice period (or indemnity in lieu) of at least 30 weeks to 2/3rds of their termination package, replacing the other 1/3rd with employability-enhancing measures (such as outplacement). The Belgian trade union for executives and managerial staff (‘CNC- NCK’) initiated legal proceedings before the Constitutional Court against this provision. However, on 25 June 2015, the Constitutional Court ruled that this provision does not constitute an infraction of the constitutionally protected rights of property and equality.
