Dibb Lupton Alsop is predicting a “winter of discontent” following a survey of 170 employers and 50 trade unions which revealed widespread fears that industrial disputes will soar. Forty-two per cent of the unionised employers surveyed had experienced industrial unrest over the past 12 months, with the number of days lost due to industrial action trebling from 415,000 the year before to 1.3 million this year.
