Woes of bank employees

Before the 1980s there was a clear path of career progression for all staff in the then state-owned commercial banks in Bangladesh. In fact, major recruitment was held to the post of clerk and cashier and based on their annual confidential report (ACR) most of them were promoted after a certain period of time. A person with graduation degree could have been promoted to the rank of officer within 5-7 years of his/her satisfactory service. Still there are lots of Senior Officers in all those banks even in the Bangladesh Bank also who had started their career as clerk or cashier.
However, with the passage of time, the system of recruitment and promotion might have been changed at all those commercial banks. As a result, the careers of a good number of people who started their jobs in 1980s with a hope of glorious life, are in a shambles. Most of them are still struggling with their lives in the same posts or just a post higher than the post they had joined and have been doing the same job for the last 20 years or so. So far as I came to know, at Agrani Bank alone the number of this type of employees is 800-1000. I do not know whether the poor guy can seek justice to the court or not. Even if it is possible, it will bring another hassle for him to continue the case for an indefinite period of time. This is simply impossible for a person like him. The situation thus compelled him to sell his father's property to adjust the loss.
I think it is humanly impossible for a person to do the same thing for the whole life. The person about who I am talking is suffering from diabetes. His eyesight has also been in trouble. He has to change his glass so frequently.
I therefore urge the authorities to please review the status of those hapless people and reclassify positions of the potential ones to the rank of a Junior Officer. Others with less calibre may either be given some clerical jobs or asked to go on voluntary retirement with some handsome benefits which they may invest for some earnings to maintain their livelihood.
