Working after the office time is dedication or inefficiency?

I think working late hours is inefficiency because it makes personal life very much miserable and realations also suffer a lot. 

yes it is. It shows lack of planning and lack of ime management skills

i dont say inefficiency it is a strong word. he/she is unable to control the situations thats it. we need to learn that art very simple fact but when it comes to action that is where u will be tested. try to control ourself that we dont at all. this is a fact

It is neither a question of dedication or inefficiency. It is a question of  duty.

Corporate professionals who work after office hours are generally well paid. Before joining such big companies, they very well knew that they will have to work extra hours in return for a handsome pay package. Those who complain even after getting such pay package are, bluntly speaking, 'laidback' or 'do not like to work hard' or 'they do not love their work'. If such people do their own business, certainly they would have to work harder, may be, even more than this ! If they want to spend time with their family, they can even go for a 9 to 5 job and remain content with a not so good pay package. So, there is no justification for complaining.

Those who really love their work, never raise issues of work-life balance. For them, their work is life. 

Veeral Gandhi Sir..!!! 

I agree with what u said here..!!!

I feel that late hours working means that either that particular employee is inefficient or work is not allotted to him properly.
