Dear Rranjan779,
Relay means shift. Rotation means shifting, turning around, rotating in some direction.
Now you question is on system of rotation of relays.
Your question is on shift change. Every company has its own system of shift change. Some compay change the shift every week some on fortnightly basis or some on monthly basic. The change may be normally in two ways, in your words rotation. This rotation may be in the direction third shift to second to first or third shift to second to first. This shift change is done on first day after the weekly off day.
Hope I have answered your question.
