My father is the secretary of our co-operative housing society for last 4 years. However due to medical reasons and health he is unable to conduct his duties as a secretary. He wish to resign from the post and has drafted a resignation letter. However, by-laws it says that, the resignation has to be accepted by Chairman and a replacement for secretary has to be made before the resignation is effective. I want to seek your advice whether he can go ahead with a resignation and stop performing his duties if Chairman (who is also working as acting one) accepts his resignation and if no other member ready to accept the responsibility? In later case, whom he should inform and take himself out from the day to day operations.
