Certain workplaces are called jobs with limited tenure. Due to physical or psychosocial risk factors, often coupled with qualification mismatches, workers cannot grow old in them. That may lead to premature exit into retirement, to a period of drawing a work incapacity pension or to a long spell of unemployment. A horizontal career change, which enables the worker to move on to a less burdening workplace while preserving social status, is a possible solution. The objective of the “Horizontal career change—a new job opportunity for older employees” project is to develop a model of career changes for workers employed in jobs with limited tenure and to implement it in the form of an information- and communication technology-based tool. Possible applications range from individual career planning, through institutionalized vocational reintegration, to personnel development in small and medium-sized enterprises.
