Seniors (elders) are required to protect, guide, lead the young ones, not propose to them. Nishabd and Cheeni Kum is Bollywood - this is real life. And this 62 year old has a FAMILY.
A 27 year old has gone to work place to work. Not to accept propoasls from seniors. And her intentions become pretty clear by the very fact that she has posted this issue here and sought help. Yes, she has to say a POINT BLANK NO.
To secure herself, she needs to have this escalated - coz how many other such girls would have had the guts to come up and report the matter? Professional matters to be handled professionally. She is not over-reacting in any case.
Also, as an HR person, it is her DUTY now to have the Secual Harrassment Policy in place (if already not done).
As human being, giving all humane considerations, it is advisable to respect the 27 year old's NO and stop approaching her for any other favuors. She has refused to accept such advances and her intentions need no proof. (AKS please second me on this).
Nonsense has to be killed FROM THE ROOT LEVEL before giving another chance for any other serious threat. The 62 year old who has a FAMILY, may rather go and show feelings there. None of us are casanovas and none of us cannot NOT control our feelings. Its on you how you exercise your controls... on yourself.
