There are many similarities between the employment laws in the Republic of Ireland, those in Great Britain and those in Northern Ireland. This is because all are common law jurisdictions and many of the more recent employment law statutes in all those jurisdictions have derived from European Directives. Notwithstanding this, there are divergences, and it is anticipated that there will be further divergence in the future. This Practice Note sets out a number of differences in employment law between Great Britain and the Republic of Ireland. However, care should be taken in dealing with matters in Northern Ireland, which operates increasingly divergent laws from Great Britain. For information on the differences between Great Britain and Northern Ireland, see Practice Note: Northern Ireland employment law.
