The number of days lost due to industrial disputes has generally declined throughout the decade of the 1990s. Figures published by the Central Statistics Office confirm that the number of days lost during the 1990s is far less than in the 1980s. This continues an overall downward trend in the numbers of days lost since the highs of the 1970s. In 1999 there were 32 industrial disputes recorded compared with 34 in the previous year. In the fourth quarter of 1999, however, there was a sharp increase in the number of days lost through industrial action. The nurses' strike in October 1999 was the largest dispute during the year and its effects can be seen in the figures for the final quarter of 1999, when 178,532 days were lost, equating to 83% of the total for the year.
