I have a bit of a dillemma.
It has been suggested to me about changing our shift roster from a three shift rotation of 6 on, 2 off, 6, 2, 6, 2, to 12, 4, 12, 4, 12, 4.
We have four shifts, three on at any given day, the fourth having their "weekend". For ease of understanding I have entered shift numbers in the table below according to the shift they are on. There is no need for weekday names because they are irrelevant, well to me anyway.
M Morning shift
A Afternoon shift
N Night shift
- Off
This is what needs to happen: I must be able to convert this structure into the above mentioned 12-4 rotation. These rules must apply:
- All crews must not work more than 8 days in a row after a 2 day break, and preferably no more and no less than 6.
- One crew must be on their days off, leaving than three crews on the job.
- The transition is to be as smooth as possible and not have any crews going into the wrong shift. IE, must follow the MAN-MAN rotation.
Here's the best I could do (again, notepad):
Unfortunately this leaves shift 1 doing 12 after 2, and shift 4 doing 10 after 2, especially going from night to morning, where the weekend is shorter in hours by nearly 24. For more information, ask me if you want times for a better understanding.
I would like everyone sliding into the roster without a problem. Moreso without too manhy extra days on or off, not including the 12 days in a row after a four.
Just on that, I tried this with a four day break after 6 on, but 4+6=10 and 12-10=2, leaving the roster two days out of sync. This meant the days off overlapped... I also don't want any more than 4 days off, and any less than 2. But not 3. So either 2 or 4 day breaks to handle it.
Also if possible, phase out the 12-4 system and go back to the 6-2 as previously described as well. This is in case the trial doesn't work. It's all well and good to say "Give everyone time off at the same time." But who would milk the cows three times a day? We have 1500 of them...
Have fun, I'll check back soon.
