The study examines retired Germans aged 60 to 85 who continue to pursue activities in retirement (so called ‘Silver Workers’). It was the objective of the study to lay an empirical basis for reasons, motivation and ideal conditions for working in higher age. Telephone interviews were conducted with 146 participants. Quantitative and qualitative methodological approaches appropriate to a broad and explorative research approach are combined. Results show a very high variety in activities of ‘Silver Workers’. Activities are either paid, or unpaid. Previous professional competencies are partially used in retirement work. Desired aspects of work are flexibility, autonomy, variety in the task, significance of the job, contact to others, perceived appreciation and personal interests. Reasons to engage in post-retirement work can be financial, social, generative, and continued personal development. Appreciation seems to be an all-embracing facet that influences almost every other motivational factor. Practical implications are critical changes to make work in retirement possible. Integration of older employees into the logic of HR policies is necessary. Thereby, the needs of older individuals should be considered. A selected key implication is to create a culture of appreciation and respect, and to promote generativity in terms of exchange between the generations. Overall, the willingness for continuative work is existent. to a certain extent, results of this study support the potential of the Fourth Pillar of pension schemes proposed by the Geneva Association (Réday-Mulvey, 2005) to be realised by flexible employment in retiring age
