U.K. EARNINGS RISE 7.6 PCT IN YEAR TO JANUARY U.K. Average earnings rose a seasonally adjusted 7.6 pct in the year to end-January after a 7.4 pct rise in the year to December, the Department of Employment said. The underlying rise was 7.5 pct after 7.75 pct in December. The January index, base 1980, was set at a provisional seasonally adjusted 190.4, down from 193.4 in December. The underlying rise, adjusted for factors such as back-pay and timing variations, had been steady at 7.5 pct from October 1985 to October 1986. Unit wage costs in U.K. Manufacturing industry rose 3.3 pct in the three months to end January, on a year-on-year basis, after a 3.1 pct rise in the three months to end December, the Department of Employment said. In January, the unit wage rise in manufacturing industries was 3.6 pct, unchanged from the December rise. The Department said the decline in the underlying rate of rise in earnings reflected the reduced significance of bonus payments in January compared with December. The actual increase reflected teacher pay settlements and industrial action in the transport and communications sectors in January 1987.
