In recent years, the proportion of the active population over 55 years of age has increased and, with it, early retirement, unemployment of older workers and senior "push" entrepreneurs. Given the repercussions at a social and economic level, the debate about the need to recover and keep seniors in the labour market is becoming increasingly rife. The aim of this study is to evaluate the evolution and European tendency towards the training and reintegration of seniors and demonstrate how formal education and continuous training can make a difference when it comes to prolonging their working life and subordinate their conditions and employment opportunities. Data from the European Working Conditions Survey between 2010 and 2021 are used and a descriptive statistical analysis and a hypotheses contrast are carried out using the Student's t test. The results show: (1) a greater effort to train and revalue seniors; and (2) that educational level and training generate significant differences in terms of the type of tasks to be performed and some variables that condition job satisfaction.
