An employee may only be required to work for 45 hours per week, excluding overtime. Anything beyond 9 hours per day is considered overtime, if you work 5 days a week. Because there are roughly 4.3-4.5 weeks in a month, that figure was used to calculate your overall working hours per month. Hence, 45 hours a week for 4.3 weeks, or 196 hours throughout the month.
