6-day schedules (part 4)

This is the fourth and final post in a series of four posts regarding 6-day schedules.  Here are the links to 6-day schedules (part 1), 6-day  schedules (part 2) and 6-day schedules (part 3).

In this post, we will look at two extremes when it comes to covering 6 days.  One uses extra staffing to cover 6 days with 40-hour workweeks.  The other uses traditional staffing for a 48-hour workweek but has a few 12-hour shifts to give an occasional weekend off.

First, lets consider a schedule that covers 6 days with 40-hour work weeks.  This is more complicated than you might think.  Why?  Well, there are 144 hours in a 6-day period.  If a crew is worth 40 hours, then you would need 3.6 crews to provide coverage (144/40=3.6).

This is accomplished by having each of your three 8-hour crews being 20% larger than the number of people you expect to show up each day.  In this way, one out of every 6 people can be off on any given day (except Sunday when everyone is off).

Here is what the schedule looks like:

6 day 40 hourYou will notice that to have 5 people show up on any given day, you need to have 6 people assigned with one of those 6 being off on that day.

First, the good news about this schedule.  Everyone gets Sunday off plus one other day that week.  This should increase alertness (compared to the alternative of only getting Sunday off and no others during the week).  That’s about it as far as the good news goes.

There are several problems:

  • Supervisors cannot match their crews unless they work all 6 days.  If they also take a day off, then provisions must be made to cover for their open position.
  • People like two days off but generally prefer then to be two days off together.  Most shift workers will place a low value on having, for example, Tuesday off as their second day off that week.
  • The staffing requirement must be a multiple of 5.  This schedule works well if you need 15 or 375 people, but it will not work if you need 7 or 18 people.
  • Night shift alertness will suffer as night shift people lose some of their “night time adjustment” during their day off.
  • Cross training is required since every combination of 5 out of 6 must represent all of the skills needed to get the job done.
  • Twice every 6 weeks there are “split workdays”.  This is where they are off the day(s) before and the day(s) after a single day of work.  Shift workers will quickly recognize that these solitary days are good days to feel…maybe a little too sick to come into work.

Companies ofter go to this type of schedule in an attempt to avoid the “high cost” of overtime; failing to realize that overtime and straight time are generally “cost equal”.

Onward…

This next schedule is an attempt to keep things simple and yet, still give the employees a full weekend off once every three weeks.  “Keeping things simple” basically says, work everyone for 6 days in a row, all 8-hour shifts.  The workforce might not like this.  Alertness, safety and productivity will suffer; but its “simple.”

Now to get a full weekend off with the smallest departure from “simple” you must work 12-hour shifts on two out of every three weekends.  The third weekend is off.

Here is the schedule:

6 day 12 hour weekendsThis schedule is only popular among those that place a very high value on full weekends off.  Working 6 days in a row is hard enough.  This schedule not only calls for that, but it makes one of those 6 days, a 12-hour day.  The result is a full weekend off once every three weeks.

This is probably not a sustainable schedule for more work places.  However, in the short run, it may be just what you need.

That’s it for 6-days schedules.  I may return to this topic again sometime.  There is certainly a lot more to say about this subject.  If you have any questions, please give me a call.  My number is (415) 265-1621.  Ask for Jim Dillingham.

6-day schedules (part 3)

This is the third in a series about 6-day schedules.  I recommend you read 6-day schedules (part 1) and 6-day scheduled (part 2) before going forward with this one.

Today’s post will begin the focus on a 12-hour schedule pattern for covering 24 hours a day, six days a week.

The premise behind this schedule is that you still only want to use three crews to cover six days, but you would rather not hire more employees.  Because of this, everyone will still have to work 48 hours a week (changing schedules does not change total hours worked.  Only changing staffing or the workload does that).  This schedule allows people to get their weekly 48 hours in by only coming to work for four days a week.

Lets look at a quick comparison:

8-hour shifts: Work 6 days @ 8 hours and get one day off per week.  Total hours worked – 48

12-hour shifts: Work 4 days @ 12 hours and get three days off per week.  Total hours worked – 48

This pattern can be worked as either a fixed schedule, a rotating schedule or and oscillating schedule.  The way it is shown here is as an oscillating schedule.  This is a schedule that has both “fixed” and “rotating” features.  In this example, the crews labeled “Days” and “Nights” are working fixed shifts.  That means they are always on Days or Nights.  The crew labeled “Day-Night” actually rotates between Day shift and Night shift (Nights on Mondays and Tuesday and then Days on Fridays and Saturdays).

There are several benefits to this schedule over a traditional 6-day, 8-hour pattern.

Employees will like it for a variety of reasons.  All will appreciate the extra days off.  The Day shift people will like having every weekend off as a 3-day weekend.  The Night shift people will like having 3 days off in a row, even though they are Sunday through Tuesday.  The rotating crew will typically be the junior-most crew.  As the junior employees, they could be looking at years before they have enough seniority to get to the Day shift.  In this schedule, they work Night shift for 2 days and then do not have to return to nights for another five days.

On the downside, the nature of the work must always be considered when looking at 12-hour shifts.  In nearly all cases, if someone can do something for 8 hours at a time for 6 days in a row with a single day of rest in between, then they can do that same thing for 12 hours at a time for 4 days a week with three days off per week to rest.

Most companies that go to 12-hour shifts will find that they need to rework some of their pay policies.  For example, if you only pay up to 8 hours a day when someone goes on jury duty, you may want to rethink that policy.

In 6-day schedules (part 4) I will return to the 8-hour idea.  We will look at a way to add people in a less-than-full-crew increment to reduce overtime.

The Weekend Warrior Trap

Weekend Warrior refers to a type of staff scheduling strategy for covering 24/7.

At its most basic level, a Weekend Warrior schedule is one that uses two crews to cover all of the weekend work so the rest of the company’s employees don’t have to.  There are several variations to this.  Here are a few of the more basic models:

  1. Two weekend crews are used.  One crew works 12-hour days on Saturday and Sunday while the other crew works 12-hour nights on Saturday and Sunday. In this way, the Weekend Warrior crews work 24 hours a week and only work 2 days per week.  The regular weekday shifts are covered by three other crews: an 8-hour day crew, an 8-hour afternoon crew and and an 8-hour night crew.
  2. Two weekend crews are used.  One crew works 12-hour days on Friday, Saturday and Sunday while the other crew works 12-hour nights on Friday, Saturday and Sunday. In this way, the Weekend Warrior crews work 36 hours a week and only work 3 days per week.  Mondays through Thursdays are covered by two  other crews: a 12-hour day crew, and a 12-hour night crew.
  3. Two weekend crews are used.  One crew works 12-hour days on Saturday and Sunday while the other crew works 12-hour nights on Saturday and Sunday. In addition to the 12-hour weekend shifts, each crew will work 2 other shifts of 8 hours at some time during the week.  In this way, the Weekend Warrior crews will get a total of 40 hours a week.  The regular weekday shifts are covered by three other crews: an 8-hour days crew, an 8-hour afternoon crew and and an 8-hour night crew.  Note that the weekend crews will augment the regular weekdays crews when they come in for their additional shifts during the week.

While there are several variations to this concept, these three represent to lion’s share of what we have seen out there.

Now that I’ve clarified the type of schedule, let’s look at The Trap.

The bait, or the thing that makes this type of schedule so attractive is that it appears to satisfy everyone involved.  The company needs 24/7 coverage and this provides it.  The employees don’t want to work weekends so you hire someone else to do it.  This satisfies your existing workforce.   People want a job and will often take any shift to get a foot in the door.  This schedule allows people to get that foot in there, provided they are willing to work weekends – done deal.

Here is the problem.  The weekend crew will under-perform unless the company over-pays.  The Trap is that once this becomes apparent (usually within the first 18 months after implementation) it is too late.  Changing the schedule will seem like a take-away and the workforce will fight it tooth and nail.

Let’s look at the “problem” a little more closely.  Here are the things we typically hear:

  • The weekend crew has a high turnover as the employees leave for better hours.
  • The weekend crew has high absenteeism. This job is typically their back-up job.  When they go on vacation from their “main” job, they simply call in sick for their weekend job.
  • The weekend crew is out of touch with the rest of the plant.
  • The weekend crew people move to the weekday crews as soon as there is an opening thus making sure the weekend crew is staffed with the least skilled and newest employees.
  • The weekend crew typically performs at about 60% the rate expected of weekday employees.
  • When the weekend crew comes in for their 8-hour weekday shifts, the plant becomes overstaffed.
  • The weekend crew typically gets a full benefits package.  This means a 50% burden rate on the weekday employees equates to a 60-85% burden rate on the weekend crew’s hours.

Some companies, in an attempt to improve retention and performance on the weekend crews will up the ante.  For example, they may pay forty hours for 24 hours of work.  I have seen companies that do this end up paying about twice as much for each hour worked by a weekend crew as they do for a weekday crew.

It looks good so companies go to it.  It doesn’t work as planned and companies can’t get rid of it.  If that’s not a trap, I don’t know what is.

If you know of anyone that is thinking about implementing a Weekend Warrior Schedule, I recommend that you have them take a look at this posting first.
