We are not reporting to 'elder or older ' we report to the post so we should not fell bad. If any one has ability, talent, sincerity they get post or designation.
For me my work is more important, I don't bother to whom I'm reporting to, whether he/she is younger or older than me. To me everybody are the employees so it will not effect my work.
From my side, My work is very important. I am not reporting to any person (who is elder/younger) but I am reporting to that designation.
I will feel normal to report a younger boss. I have nothing to do with his/her age.
Knowledge is the only thing which matters to me.
