6.It may be true that there was general exemption granted earlier by the Government in G.O.Ms.No.1811, Labour Department dated 23.09.1986, however, subsequently, the Government appears to have taken a different decision as is evident from the Government Letter No.355/C1/2017 dated 26.07.2017. In the said letter which is addressed to the Managing Directors of all State Transport Undertakings, including the appellant, they were directed to implement the orders passed by the Government in G.O.(2D) No.91, Labour and Employment (J1) Department dated 12.12.2013 and sanction minimum wages prescribed in the said Government order to all the temporary employees of State Transport Undertakings (ie., Reserve Drivers & Conductors and 240 days daily wages Drivers & Conductors and Technical Staff) by complying with the orders passed by this Court in W.P.[MD]No.21436 of 2016. Though, it appears that the said writ petition pertains to a case arising out of a writ petition filed by the Arasu Pokkuvarathu Madurai Thozhilalar Sangam, Madurai, the Government letter issued by the Additional Chief Secretary to Government, Transport Department dated 26.07.2017, covers all the State Transport Undertakings.
