Assistant/Senior Technical Assistant/Chief Draughtsmen. Further, a 20 point roster was to be followed in the chronological order of Foremen, SSA, STA and Chief Draughtsmen. Later, vide OM dated 16.06.1998, on the recommendations of the Board of Arbitration, the petitioner allowed 41% of STAs to be placed in the pay scale of Rs. 2375-3500 w.e.f. 01.01.1988 but, according to the respondents herein this was only a placement and did not amount to promotion, as the benefit of FR 22 (1) (a) was not extended.
