Not sure I agree with that!
Wow! Working long hours is something to be "ashamed" of? That is an interesting view of a manager working long hours. I have a couple of other words I might assign to such an activity: how about "commitment and loyalty?"
I am going to guess, that most of you that don't believe in working long hours, don't know what it's like to start a company with limited resources? I am also going to postulate, that it is likely, that many of you probably are managers or are looking to become managers, which of course makes sense as to why you wouldn't agree with working long hours. It is also possible that many of you could have a manager that works long hours and perhaps their "work ethic" makes you feel guilty?
I agree that boasting about working long hours comes from the ego and therefore does not speak highly of the individual, but let's not condemn someone that is working long hours because they are committed to the company they work for and recognize that they are doing what it takes to get the job done.
In today's economy, with many companies going out of business and many others struggling just to survive, companies are required to do more with less - sometimes (for long periods at a time) working long hours is part of doing more with less! Some of you might say that you just need to work smarter. You always need to work smarter but sometimes it's not enough.
