The respondents have opted for revised pay scales of the corporation. Before revision, the respondents were paid salaries on par with the corporation employees and the second respondent paid interim relief of Rs.25/-pending implementation of the revised pay scales. The first petitioner announced the adoption of revised pay scales on 10.01.1980 to all its employees. The Government of Andhra Pradesh passed G.O.Ms.No.54 dated 30.01.1981 and in that annexure also in column No.8, the basic pay payable to the attenders is shown as 295-5-345-10-425 working at Heat Setting Plant, Machilipatnam.
