This document discusses various components of employee salary including salary deferral, gratuity, provident fund, and group insurance. Salary deferral allows employees to set aside a portion of their income for retirement. Gratuity is a lump sum amount received by an employee upon retirement or leaving based on years of service. Provident fund requires equal monthly contributions from employees and employers that accumulate over the employee's career. Group insurance provides a lump sum payment to an employee's family if the employee passes away before retirement.
