The original allocation for 1981 under subhead A, which covers wages and salaries, was £470,000. By the end of September 1981 all but £4,400 of this allocation was spent. Put in another form, the original allocation was totally inadequate. This Supplementary Estimate is needed for the following reasons: there was a substantial pay award granted to technicians from 1 January 1979. and to chemists with effect from 1 January 1980, amounting to expenditure of £145,000 in 1981. There was a consequential Government decision—your decision — to reduce all the 1981 Estimates by 5 per cent and this led to a reduction of £25,000 in Subhead A of the State Laboratory Vote. In addition there were special pay increases with arrears payable to clerical and subordinate staff amounting to £6,000. This was during your period of negotiation.
