This paper reveals the scope and patterns of mobility on the labour market in the Czech Republic in between 2002 and 2013. Occupational and sectoral mobility are analysed using the data from the Labour Force Survey. The LFS data were adjusted into a form of longitudinal data enabling to follow an individual in four consecutive quarters. The frequency of mobility on the Czech labour market and its development during different phases of business cycle is studied. The level of mobility is examined in the entire population of the employed as well as among subgroups defined predominantly by socioeconomic characteristics. Patterns of labour mobility revealed by this paper are discussed in the light of similarly focused studies from abroad and theoretical approaches toward labour mobility.
