In the modern world of work companies restructure faster and more frequently than previously. In doing so, they carry out measures that are intended to strengthen the company's productivity by reorganising technical and organisation processes, and frequently by changing the company's structural layout as well. Departments are merged or reorganised with the aim of being able to carry out the pending tasks better and/or at less cost. In most cases, they are downsized as well, either through actual dismissals or in a socially acceptable way by means of early retirement, or not extending fixed-term employment contracts. Employees often sense that their work becomes more intensive through restructuring, because the same, or even more and more demanding work, has to be carried out with reduced staff numbers. In this Factsheet we show that restructuring can increase mental strain during work and impair the health of employees.
