Modified Work Arrangements
Employers and employees can agree to average the hours of work for up to a four-week period.
In some situations workplaces may need an averaging of hours permit, not a modified work arrangement. A permit requires approval from the Director of Employment Standards. A modified work arrangement does not.
1. What is a Modified Work Arrangement (MWA)?
A modified work arrangement (MWA) is an agreement on a set schedule between the employer and an employee or a group of employees that averages hours of work over a designated period of time. This arrangement is modified from the standard eight hours a day and 40 hours per week of hours of work before overtime. The MWA is an agreement, not a permit. MWAs increase workplace flexibility by allowing employers and employees to compress work time in return for more time off for employees.
The MWA must specify when overtime will apply for each day and week or number of weeks; however, the arrangement cannot include scheduled shifts exceeding 12 hours in a day.
The employer may define the day as a calendar day or any period of 24 consecutive hours starting at the time the employee is scheduled to begin work. It must be included in the work schedule.
MWA rules require a set work schedule agreed to in advance. Schedules that fluctuate depending on the needs of the day and can’t be set and agreed to in advance are not appropriate for an MWA.
An MWA may average:
- 40 hours over one week;
- 80 hours over two weeks;
- 120 hours over three weeks; or
- 160 hours over four weeks.
An MWA allows employees to work more hours in one part of an averaging period in return for more time off in another part of the same averaging period. Overtime applies once employees work more hours than stated in the MWA’s daily limit or averaging period.
A permit from the Director of Employment Standards is required for a schedule that has an averaging of hours period longer than four weeks.
Examples of a Modified Work Arrangement
Using an MWA, a standard work week as described below can be modified.
| Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
| 8 | 8 | 8 | 8 | 8 |
Employers and employees can instead agree to average 40 hours over a week, with overtime after 12 hours in a day. In this example, employees must be scheduled to work three 12-hour days and one four-hour day during the one-week averaging period. Overtime would be payable for any work performed after 12 hours in any day or work performed after 40 hours in the one week averaging period.
| Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
| 12 | 12 | 12 | 4 |
Employers and employees can also agree to average 80 hours over two weeks, with overtime after 12 hours in a day. In this example employees work a set schedule of a combination of 12-hour days and one eight-hour day during the two-week averaging period. Overtime would be payable for any work performed after 12 hours in a day (and eight hours on the second Wednesday) or work performed after 80 hours in the two week averaging period. If the eight-hour shift is earlier in the rotation, overtime is owed if the employee works more than eight hours on that day.
| Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
| 12 | 12 | 12 | 12 | |||
| 12 | 12 | 8 |
2. Requirements for MWA Agreements
Agreements must:
- be in writing;
- be signed by the employer and employees agreeing to the arrangement, or a majority of the employees affected;
- specify the number of weeks over which the hours will be averaged;
- specify the daily hours of work after which an employee becomes entitled to overtime (this must match the affected employee's daily schedule);
- specify the work schedule that reflects the daily and weekly hours agreed to by the parties;
- provide a start date and an expiry date for the modified work agreement; and
- be in place at least one week before any work schedule changes.
In addition, agreements:
- cannot be longer than two years;
- cannot require employees to work more than 12 hours in a day without overtime pay; and
- must be given to all employees covered by the agreement, and/or posted in the workplace.
Regular overtime rules apply if the conditions set out in the modified work arrangement are not met or maintained.
A permit from the Director of Employment Standards is required to arrange an averaging period longer than allowed by a MWA, or wishes to vary the rules for days off per week.
A collective agreement's hours of work provisions are also considered a MWA, however the above requirements are not needed as they will be covered in the collective agreement.
Managerial and professional staff are exempt from overtime so can't be part of a MWA.
Unionized employees are eligible for overtime based on their collective bargaining agreement.
Employees Working Fewer Than 30 Hours Per Week (Part Time)
Employees who work on average less than 30 hours per week may be part of a modified work arrangement.
