Eurostat speaks of ‘labour market slack’. The International Labour Organization (ILO) calls it ‘labour underutilization’. Both organizations also use terms like: ‘unmet demand / need for employment’. Semi-unemployed are named by Eurostat as ‘potential additional labour force’ by ILO as ‘potential labour force’.
