Overtime, incentive pay and shift pay now account for an increasingly small proportion of overall pay packets, according to the Labour Market Trends survey.
The study by the Office for National Statistics, based on data from the New Earnings Survey, shows that additional payments are in decline. In 1992, they accounted for 10.8 per cent of gross pay, but this figure had fallen to 8.9 per cent by 2002.
Overtime pay made up 4.1 per cent of gross weekly pay last year, compared with 5.7 per cent in 1992.
Overtime pay is greatest in the agriculture sector, where it makes up 13 per cent of gross pay. Incentive pay is most prevalent in the financial intermediation sector, where it accounts for 8.9 per cent of basic pay.
Shift pay makes the smallest contribution to the overall pay packet in the health and social work sector, amounting to just 3 per cent of gross pay. www.statistics.gov.uk
