The Employee Participation Act (MBL) requires that employees and union representatives be involved in major organizational changes. For a Chief of Staff (CoS), this means that the EA work must be integrated with MBL processes, especially during change initiatives that affect work processes, IT systems, or organizational structure. The CoS should inform and involve relevant parties early through dialogue meetings, workshops, and joint analyses of how changes impact the business. EA models can be used to visualize consequences and provide a basis for discussion. By working transparently and documenting the decision-making process, it ensures that the MBL requirements are met and that the change gains broad support. This reduces the risk of resistance and contributes to a smooth implementation of new solutions.
