Unionists are to press for guaranteed wage rises at an employment summit today, while bosses said they will seek an increase in imported labourers. Confrontation is expected when more than 100 representatives of legislators, the Government, business and union groups exchange views at the conference hall of the Central Government Offices. Legislator and chief executive of the Hong Kong Confederation of Trade Unions Lee Cheuk-yan said unionists would highlight negative wage growth in an attempt to draw the attention of the conference to the employee's side. The Joint Business Group on the Labour Situation said it would continue to press for relaxation of regulations on the labour importation issue. The chairman of the Retail Management Association, Rodney Miles, said his group had submitted papers to the Government to show the territory was suffering a labour shortage.
