Help me make an equitable schedule

Can someone help me sort out this problem:

At my job, our work schedules are set every eight weeks.

In those eight weeks, we have to work 4 Saturdays and 2 Sundays.

And 2 of those Saturdays have to be in each of the two four-week sections of those eight weeks, Weeks 1-4 and 5-8.

And the 2 Sundays have to be split between weeks 1-4 and 5-8.

There are five people who are scheduled.

Presuming that no one asks for vacation time, what is the most equitable distribution possible of people getting a consecutive Saturday and Sunday off?

Sunday is the beginning of the work week and Saturday is the end.

My numerous charts I have prepared can’t figure this out.

How many can you have working at once?

How many people work each day?

It’s not that hard to work out, except that with five employees, there seem to be days where there is an extra worker.

I’ve worked out a system where in weeks 1, 4, 5, 8 there are three workers on Saturday. Weeks 2, 3, 6, 7 have two Saturday workers.

Similarly, in the same system, I’ve got two workers on weeks 1 and 4 on Sunday, and one Sunday worker during the other weeks.

With four employees, this works out perfectly. The fifth employees is kind of a monkey wrench.

Here’s a visual aid:



	Wkr 1	Wkr 2	Wkr 3	Wkr 4	Wkr 5
	------	------	-------	-------	-------
1	A, U		A	A	U
2		A, U		A	
3	A		U		A
4		A	A	U	A

5	A, U		A	A	U
6		A, U		A	
7	A		U		A
8		A	A	U	A


Saturday = A
Sunday = U

Workers 1 and 2 get four complete weekends weekends off. The other three employees get two complete weekends off.

Maybe we can use this scheme as a start, and work on trading some spots around.

We get part-time people to fill in where needed. Normally, there are 3 full-timers on Saturday and 1 or 2 on Sunday.

Bob, using full-timers only, I can come up with three employees only half of the time. Can we allow a part-timer to fill in every other Saturday? Otherwise, some of your full-timers will work 5 or more Saturdays in an eight-week period.

Um … in the post above, I was adressing strictly Saturday work … in case it wasn’t clear.

Bob indicated that part-timers can work Sundays if needed, so Sundays seem to licked.

The primary goal is keeping people to the scheduling guideline. That is a union regulation. The Powers That Be will provide extra help as needed.

OK then, Bob, try this:



	Wkr 1	Wkr 2	Wkr 3	Wkr 4	Wkr 5
	------	------	-------	-------	-------
1	A, U		A	A	U
2		A, U		A	
3	A		U		A
4		A	A	U	A

5	U	A	A	 	A,U
6		A		A, U	
7	A		U		A
8	A	U	A	A	


This way, over an eight-week period four of your full-timers get three full weekends off, while the fifth gets two full weekends off.

Every eight-week period, rotate the worker who gets the two weekends off (in the chart above, it’s worker 3). Over a period of forty weeks, all five full-timers will get 14 full weekends off.

Also, looking at the last chart, no one has to work more than one weekend in an eight-week period. Over a forty-week period, all five full-timers will work only four full weekends.

And for the worker who gets the two-weekends-in-eight-off (wkr 3)? The trade-off is that s/he doesn’t have to work any full weekends during those eight weeks.

Thanks.

I hope I can keep everyone happy.
