TRADE unionists yesterday accused the Government of encouraging employers to stamp out staff unions. In a petition to the Attorney-General's Chambers, the chief executive of the Hong Kong Confederation of Trade Unions (HKCTU), Lee Cheuk-yan, said the Legal Department had refused to prosecute companies which the unions believed had persecuted staff for being members of unions. The HKCTU had complained to the Labour Department and the Legislative Council Complaints Unit about supermarket chain Wellcome and Cathy Pacific Airways. The union claimed the airline had dismissed an employee because of her connections with a union, and said the supermarket chain had unfairly dismissed two staff because of their connections with a union. Mr Lee said one summons had been issued against the supermarket and no action had been taken against the airline. He claimed the legislation against union discrimination existed in name only if the Government was not prepared to act on it.
