In 1975, a short-term strike hit the ITV network in the spring, due to a dispute over the payments agreed before the government-imposed pay freeze came into force. A 19% pay rise had been agreed between the ACTT (Association of Cinematograph Television and Allied Technicians) union, and with the ITV companies in July 1974. The union alleged that £231 of this deal was still owed to its members, and should not have been affected by the pay freeze. The strike took place from 6.00 am on 23 May (except for London Weekend Television, Tyne Tees Television, and Westward Television, where ACTT members ignored the strike). At 6.00am on 26 May, when striking workers came back to work, they were locked out by management. Normal service resumed on 30 May for all ITV stations, except for Scottish Television, whose staff refused to return to work after the lockout finished on 29 May. Staff eventually returned on Monday 9 June In 1978, company profits had risen by 21.8% in the first six months of the year, allowing for an increase in local programming.
