The number of employees with a flexible contract is increasing. The aim of this study was to investigate how types of flexible contracts and job insecurity were related to vitality and productivity in comparison to permanent contract. Longitudinal analyses were used to study whether the change of contract influences vitality and productivity over time. Cross-sectional analyses were used to investigate the relationship between vitality, productivity and job insecurity. The data were derived from the ‘Cohort Study on Sustainable Employability’ (CODI) from TNO. 15,185 participants in 2016 and 9,698 in 2017 from 15 to 74 years old were included in this study. Employees with a fixed period and agency contract have lower vitality because their job insecurity was higher. Employees with a fixed period, agency and on-call contract have lower productivity than permanent employees (partly) because their job insecurity was higher. HR professionals can play a role in order to strengthen the position of flex workers in the labour market.
