Hi,
The short prose that I put up earlier was actually a reply to a question as to whether or not six-day shifts is workable, and if it is why aren't many companies doing it.
How does this sounds:
Most companies aren't running six-day shifts because either they've experienced it or they would have been advised that if they ran three 6-day shifts, at one of the shift changes their staff would experience a very short day off.
Thanks.
Regards,
Jeeva
