When comparing oilfield jobs, most people focus on hourly wages.
But the working rotation can have an equally important effect on your annual income and personal life.
Two employees may earn exactly the same hourly wage and work twelve hour shifts.
Yet one may spend approximately half the year working, while another spends three quarters of the year on scheduled shifts.
That creates a major difference in annual earnings, time at home, and fatigue.
Three rotational schedules commonly discussed in oil and gas are 14/14, 20/10, and 21/7.
Each offers a different balance between working time and days off.
So which one should you choose?
To answer that, you need to understand how the schedules work and how many paid hours they can produce.
What Does a 14/14 Rotation Mean?
A 14/14 schedule means working fourteen consecutive days followed by fourteen days off.
The cycle repeats every twenty eight days.
This provides equal amounts of scheduled working days and days off.
Over a typical year, the long term average is approximately 183 scheduled working days and 182 days off.
If you work twelve paid hours per working day, this represents approximately 2,190 paid hours annually.
The actual total may vary based on the calendar, travel, leave, and employer arrangements.
Advantages of 14/14
The biggest advantage is the extended time off.
You can spend two weeks at home between rotations.
This can make it easier to manage family responsibilities, personal activities, and appointments.
The schedule may also provide more recovery time following demanding work periods.
Disadvantages of 14/14
The main disadvantage is fewer working hours compared with 20/10 or 21/7.
If your hourly wage is relatively low, annual income may be lower than expected.
Travel time can also reduce your usable days off.
For example, if you spend much of the first day travelling home and return a day before the next shift, you may have less than fourteen full days at home.
What Does a 20/10 Rotation Mean?
A 20/10 rotation involves twenty consecutive working days followed by ten days off.
The complete cycle lasts thirty days.
Approximately two thirds of the rotation consists of working days.
Over a typical year, this represents approximately 243 scheduled working days and 122 days off.
At twelve paid hours per shift, the long term average is approximately 2,920 paid hours annually.
Advantages of 20/10
A 20/10 rotation provides more working hours than 14/14.
That can increase annual earnings when the hourly wage and other conditions are comparable.
The ten day break also provides a meaningful period away from work.
For some employees, this is an acceptable compromise between income and time at home.
Disadvantages of 20/10
Twenty consecutive working days can be demanding.
Employees working twelve hour shifts may experience significant cumulative fatigue.
Travel and recovery can consume part of the ten day break.
The schedule also requires spending more time away from home than 14/14.
What Does a 21/7 Rotation Mean?
A 21/7 rotation involves twenty one working days followed by seven days off.
The cycle repeats every twenty eight days.
Three quarters of the scheduled days are working days.
Over a typical year, this represents approximately 274 working days and 91 days off.
At twelve paid hours per working day, the long term average is approximately 3,285 paid hours annually.
Advantages of 21/7
The greatest advantage is the number of working hours.
If the hourly wage is competitive and work remains available, the schedule can produce substantial annual earnings.
Some workers choose this type of rotation while pursuing a specific financial goal, such as paying down debt or saving for a house.
Disadvantages of 21/7
The schedule provides much less time off.
After twenty one consecutive shifts, employees may need several days simply to recover.
Travel can further reduce the amount of usable personal time.
The schedule may also make family and social commitments more difficult.
It can be challenging to sustain over many years.
How Much Can You Earn on Each Rotation?
Consider three hypothetical jobs paying $35 per hour.
Assume twelve paid hours per shift and continuous employment throughout the year.
For this comparison, all hours are calculated at straight time.
Overtime premiums, bonuses, and other compensation are excluded.
Earnings on 14/14
Approximate working days annually: 183.
Approximate paid hours annually: 2,190.
At $35 per hour, estimated annual gross wages are $76,650.
Earnings on 20/10
Approximate working days annually: 243.
Approximate paid hours annually: 2,920.
At $35 per hour, estimated annual gross wages are $102,200.
Earnings on 21/7
Approximate working days annually: 274.
Approximate paid hours annually: 3,285.
At $35 per hour, estimated annual gross wages are $114,975.
These are simplified illustrations, not guaranteed annual salaries.
Actual compensation depends on the employer, overtime rules, working hours, and availability of work.
The difference is significant.
At the same hourly wage, 21/7 produces approximately $38,325 more gross annual wages than 14/14 under these assumptions.
But it also requires approximately 1,095 additional paid working hours.
You are earning more because you are working substantially more.
Which Rotation Offers the Best Work and Life Balance?
If time at home is your priority, 14/14 offers the greatest amount of scheduled time off among these three schedules.
It can be attractive to people who want extended periods with family.
A 20/10 schedule provides more income potential while maintaining a relatively long break.
A 21/7 schedule prioritizes working time.
However, the best schedule depends on personal circumstances.
Some people prefer longer periods at home.
Others prefer more frequent returns.
The type of work also matters.
Twenty consecutive days in a demanding outdoor role may feel different from twenty days monitoring equipment at a processing facility.
Think about whether the schedule is sustainable rather than simply attractive for a few months.
Does Overtime Work the Same on Every Rotation?
No.
Overtime entitlements depend on the jurisdiction, occupation, employment arrangement, and applicable rules.
In Alberta, the general overtime framework uses eight hours per day or forty four hours per week, whichever is greater.
However, special provisions apply to certain oilwell servicing employees.
For employees covered by Alberta’s oilwell servicing rules, overtime generally applies after twelve hours per day or 191 hours per month, whichever is greater, subject to the detailed requirements.
Other exceptions and valid averaging arrangements may also apply.
In the United States, overtime depends on applicable federal and state law and the employee’s legal classification.
Do not assume every twelve hour shift includes four overtime hours.
Ask the employer how overtime is calculated before estimating annual earnings.
How Do Camp and Travel Arrangements Affect the Rotation?
Two jobs with the same schedule may offer very different working conditions.
One employer may provide flights from Edmonton, camp accommodation, and meals.
Another may require employees to drive to the reporting location.
Some companies pay travel time.
Others do not.
You should determine whether the first and last days of the rotation involve work or travel.
If you must leave home early to reach the worksite, your actual time at home may be shorter than the schedule suggests.
Travel expenses can also reduce the financial benefit of a higher paying rotation.
Which Rotation Is Best for Saving Money?
At the same hourly wage and paid shift length, 21/7 offers the highest potential gross earnings.
But the schedule alone does not determine how much you save.
A 14/14 job may offer a much higher hourly rate.
A 20/10 employer may provide better bonuses or benefits.
A 21/7 position may have inconsistent work between projects.
You also need to consider accommodation, transportation, and personal expenses.
The best schedule for saving money is the one producing the strongest realistic financial result after necessary expenses.
Which Rotation Is Better for Long Term Health?
Long consecutive working periods can increase the importance of managing fatigue, sleep, and recovery.
Night shifts, heavy physical activity, weather conditions, travel, and workplace demands can make fatigue more significant.
Workers and employers need to follow appropriate fatigue management and safety requirements.
If you are considering a demanding schedule, ask yourself whether you can maintain it safely over the long term.
A schedule that helps you reach a short term financial goal may not be the one you want for the next fifteen years.
Final Thoughts: Which Oilfield Rotation Should You Choose?
A 14/14 rotation provides the most scheduled time off among these three options.
A 20/10 rotation offers more working hours while retaining ten days off between assignments.
A 21/7 rotation provides the greatest number of scheduled working days and the highest potential earnings when other conditions are equal.
But choosing an oilfield schedule should involve more than calculating the biggest paycheque.
Compare the hourly wage, overtime rules, travel arrangements, benefits, and expected annual working hours.
Also consider the effect on sleep, recovery, family responsibilities, and long term health.
The best rotation is one that offers a realistic combination of income and time off that you can sustain.
