Calculating Average Working Hours
Calculating average working hours is very simple, as this post will make clear.
Average Working Hours Per Week
To discover the average number of hours you work in a week, divide the number of hours you have worked over a period of time by the number of weeks in that period (excluding rest days). For most adult workers, this period should be 17 weeks and the average number of working hours in a week should not exceed 48.
Average Working Hours Per Day
To discover the average number of hours you work in a day, divide the number of hours you have worked over a set period of time by the number of days you were required to work during that that period. As a night worker, this period should be 119 days (17 weeks) and the average number of working hours in a day should not exceed 8.
Working Hours within Shift Cycles
To discover your average working hours from shift cycles requires a little more effort.
To start with, divide the number of days in a period of time by the total number of days in your shift cycle to discover how many cycles you have worked in that period. Then multiply the number of hours you work in a cycle by the number of cycles you have worked and add any overtime – this will be the total number of hours you have worked in the period of time.
Subtract the number of rest days to which you are entitled from the total number of days in the period and, finally, divide the number of hours you have worked by the number of days you have been required to work. The resulting number is the average number of hours worked in a day which, for night workers, should not exceed 8.
