Not everyone working in IT sector is stressed. There are many who work like employees in other sectors also.
It is those who are in a project with deadline who have to work with stress. That is there in all other sectors also.
Working in shifts, doing overtime were all there since decades. Even I had worked in round-O-clock shifts., in one job where I was to do overtime if needed. That means I will be away from home for about 16 hours. Then have to return, do all other things including sleep in the next less than eight hours and again be off to work for the next shift.
There was a time that if we found lights inside an office by 9 pm or 10 pm, we could be sure it was a bank and mostly officers used to sit to finish that day's work and prepare for many things where deadline was there . That also not getting any overtime compensations. But they all suffered silently then( and some even now).
Doctors had to work extended hours and cannot stop working at a dot when patients are waiting. They will have the stress of surgery and complicated cases. Many government employees have to work with stress. What about Police and army?
Then why the IT sector got the publicity of working under stress? That is because, IT sector employees were freshers, in their twenties, recruited in mass scale. So almost every home had one in IT sector suddenly. Most of these were working for Projects with deadline, Business outsource for other countries with different time zones and in service solutions. So these youngsters who did not know about how people were working in hardship jobs and in round the clock shifts made it a point of discussion, because they lost their time to socialise which they were doing as students. Their families also discussed and spread it that way, because for them also it was new experience. But one should also accept that IT sector employees were given very good compensation which other sectors could only dream.
So it is just a myth or exaggerated propaganda that only IT sector people work under stress. Others too work under stress, tension and compulsion and many times with lesser compensation.
Let us keep faith on ourselves and work sincerely, not leave everything to fate.
