The official website of the EU has chronicled the march of the Irish Language towards full status within the European Union:
" Irish has been an EU language since 2005 with a limited status, meaning that only a small share of documents were translated into Irish. In December 2015, at the request of the Irish government, the Council decided to increase the material available in Irish to progressively reach full status for the Irish language in the EU by 2022."
This has led to an increase in the number of EU staff and contract employees who are required to be fluent in Gaelic:
" The number of Irish-language staff in the EU institutions’ language services rose from 58 to 102 between the end of 2015 and mid-2019. Although it remains a challenge to meet the staffing targets for permanent staff, the EU has taken a flexible approach by recruiting and training temporary staff. Four open competitions (EPSO) were organised for permanent staff and 14 selection procedures for temporary staff."
