For the biggest savings with the smallest effort, with zero risk due to current job holders being completely ignorant of the oil industry, EM should PIP the Executive Board members that pay each other millions of dollars per month.
If Indian workers are so capable, hire Suresh and Rajendra as the next CEO and CFO for less than $35,000 per year. EM could pay an entire Indian board of directors for a year for less that one US executive is paid in a week.
