This Research InBrief summarises some recent NERI research on employment arrangements in Northern Ireland. The aim of this work was to examine trends and patterns in employment arrangements in Northern Ireland, with particular attention given to the share of the labour market which is comprised of full- and part-time permanent workers, full- and part-time temporary workers, and full- and part-time self-employed workers. The results of this study show that the composition of employment in Northern Ireland has undergone considerable change in recent years. There has been an overall decline in the share of labour market which is comprised of workers employed in the traditional ‘standard’ employment arrangement i.e. full-time, permanent, regular, and an increase in more insecure forms of employment.
