From MITI: Just a reminder that if you hire an employee in August with a date other than August 1, the system will prorate the earnings for the month. For example, if an employee’s first day is 8/15/2016 and is entitled to a full month pay, the system will prorate their monthly pay. You will then need to review the paycheck on August 19 (after Pre-Calc 1) and make the adjustment to bring it to full pay.
