MAN HOUR.pptx Calculating Man Hours Per Month

WHAT IS MAN-HOUR?
Man hour is the total hour worked over a specific period of time or the amount of work performed by the average worker in one hour. It is used for estimation of the total amount of uninterrupted labor required to perform a task.
Man hour is an integral factor in measuring Health and safety performance.
An organization that records 5 LTI in every 10,000 man-hour every 3 months and the organization that record 10 LTI in every 100,000 man-hour every 3 month poses different Health and safety performance level. Judging by the man-hour and the LTI recorded, the second organization has a better Health and Safety performance.

Man-hours exclude the breaks that people generally require from work, e.g. for rest, eating, and other bodily functions or public holidays. They count only pure labor.

How To Calculate Man Hours
Man hours formula = Total hours work a day per worker x Total number of workers x Total numbers of days worked over the specific period of time

For a day: Total hours work a day per worker x Total number of workers
Consider that:
Number of hours worked a day per worker: 8 hours
Total number of workers: 20 workers
Man Hour A day = 8 x 20
= 160 Man Hour.

Calculating Man Hours Per Month
Mathematically, having in mind the formular for calculating man hour.
Recap:
Total Man Hour = Total hours work a day per worker x Total number of workers x Total numbers of days worked over the specific period of time
For a Month: Total hours work a Month per worker x Total number of workers
N/B:
Average daily working hour = 8 hours
Average days in a week = 5 Days (minus weekends and public holidays).
Average weeks in a month = 4 Weeks
Total hours work a Month per worker = 8 x 5 x 4
Total hours work a week per worker = 160
== Assuming 8 workers worked
Man Hour the month = 160 x 8
Total manhour for the month = 1280 Man Hour.

Hours worked per day x number of staff x total number of days worked in the month = Manhour
8hrs x 9 staff x 20 days = 1,440 Manhour
Excluding public holiday

There are situations where an employee work for more than 8 hours a day, in this case the number of hours work will be used instead of the average daily working hours.

In GNL, we have day staff and duty officers
Man hour for day staff
11 staff x 8hrs x 20 days = 1,760 Man hour

Man hour for duty officers
19 staff x 24hrs x 14 in a month
19 staff x 12hrs x 31 days = 7,068 Man hour

1,760+7068 = 8,828 Man hour in month of March by GNL


Significance of Manhour
One significance of manhour is that by dividing the total number of man-hours by the total number of workers available, the man-hour concept has the advantage of allowing one to calculate the impact of staff changes on the total amount of time needed for a task. A team of two workers will finish a task that requires twenty man-hours in ten hours, whereas a team of five workers will finish it in four hours.
