I meant billing 8 hours per day compared to 6 hours per day.For a services company , The project needs to get extended as the man hours needed will take more time for 6 hr work day. So company needs to hire more heads as per current 8hr/day estimation but at the same time salary of the employees stay same.So the point is ,wouldn't be a lose if the company's business model is selling man hours ?
