I really don't think a rotating shift system or any other shift other than 9 to 5 really works. The effect are far reaching. I worked in shifts for the past 7 years, and my health suffered a lot. I finally called it quits after 7 years of shift system and settled on a 9 to 5 job. The work timings of call centres are horrible, and anyone working for long-term in a call centre is bound to suffer much more than he thinks. Call centre jobs can be only a stop-gap arrangement until you can find a better job. All that money a call centre employee gets will be used for hospital bills later on. So, what good is that money if you don't have health. And why the hell should we sacrifice so much for our white masters abroad?
