20. One more argument advanced by Mr.D.Sivaraman, learned counsel, is that the charge memo, which was the subject matter of consideration by the first respondent, is not the only charge memo, but there were other charge memos, which were issued to the second respondent, which had ended in imposing punishment of censure / warning and the charges were for absence from duty. Copies of charge memo and the orders of censure have been filed by the learned counsel appearing for the second respondent in the form of a typed set of papers and we find that invariably the absence from duty ranges between one to three days. Though such charge memos were issued, the appellant Management continued to engage the services of the second respondent and it is not their case that he was disengaged or no employment as reserve conductor was issued after the issuance of the charge memo. Only one such charge memo dated 13.11.2013, ended in an order of punishment of dismissal from service. However, approval for such dismissal was denied by the competent Authority, consequently, the second respondent was deemed to be in employment of the appellant Corporation subject to the challenge to the order declining approval, dated 23.08.2017, which is now pending in a writ petition before this Court in W.P.(MD) No.16167 of 2018 filed by the Management.
