THE Fool's Day on April 1, 1998, is going to be a serious occasion for the underpaid employees at the Rs 577-crore Indian Hotels Company, better known as the Taj group, the country's largest chain of hotels. That will be the day when a new personnel management system developed by consultancy firm A.F. Ferguson will be introduced. For the 12,798 employees of the group, this will be sweet music: compensation packages are expected to match industry norms.
