It is the chair that is respected not the chair person.In employment this is a very common and known fact that almost all the employee show respect to their seniors because of their position and not as a person. Many seniors are aware of this, but few live in a fool's paradise that they get respect from their juniors because they have now become senior due to their work and capability.
This realisation comes only once we leave the job. All the perks, all the facilities, all the attention, smiling faces, all salutations, everything vanishes once we leave the position we held. Now all these goes to the next person sitting on that chair or position.
We must realise and keep this in our mind even before we go for a job. Everything is not as it seems, just focus on your work and be respectful to all. There will be some exceptions but mostly the general nature in an office is of respecting the chair/position only and not the person sitting on that chair/position.
