Microsoft’s compensation moves have created a haves-vs.-have-nots culture. Newbies work for comfortable but not overly generous wages, while veterans have a lucrative treasure chest of stock options. Now a new pay scheme, scheduled to go into effect this fall, threatens to make the gulf even wider. If they meet incentive goals, the 120 or so vice-presidents will receive an eye-popping $1 million in salary a year, and general managers, the next level down, will get $350,000 to $550,000, according to a high-ranking source. But the rest of the staff is paid at market rates.
