Different generations have their own view on working. You like it or not, working is part of our live. No work = No life. However, this equation has since changed to "Working = No life". Do you agree?
Generally, those born in 70s were perceived to be loving their job. They work hard mainly because of 3 meals/day. For them, a secured life means having a stable job with stable income. They believe that with every efforts you put in, that will reward you back later. As such, over time (OT) is nothing for them.
As a responsible 70s, losing their job is a serious matter they tend to avoid. That's why they usually found another job first, before resigning.
How about 80s?
