Although project requirements may dictate schedules, a Northstrat employee is only required to work an average of 8 hours per weekday over the course of a month. For example: John worked 12 hours on June 1st to meet a project deadline. On June 15th, John only worked 4 hours because he left early for a long weekend.

The IBA can be used for such things as: IBA Benefits accrue each month in the amount equivalent to 50% of the employee’s monthly compensation rate.
