Ageing of the population is a universal problem. A common solution to deal with the negative effects of an ageing population is to keep citizens employed longer by raising the retirement age. However, the employment rate of people over fifty remains relatively low in many countries. This study aims to find out which barriers people over fifty experience in the labour market that hamper employment, explain inactivity, and make it more difficult to find a job. We examine these barriers using an online survey with 3 963 Flemish individuals over fifty. We find that both working, inactive, and unemployed individuals mainly experience work-related barriers on the labour market. More concretely, more than two-fifths of the working respondents indicate that a lack of (1) a good work organisation (44.1%), (2) a good manager (43.1%), and (3) appreciation (41.9%) hinders them from doing their job. Inactive respondents also give these barriers as the main explanations for inactivity. Furthermore, it appears that 71.0% of the job-seeking respondents experience age discrimination in hiring as a barrier and that 35.2% of these respondents indicate that their high salary expectations, according to their impression, makes finding a job more difficult. The extent to which one experiences certain barriers also seems to differ by gender and level of education.
