company benefits go beyond the person in most cases, unless you are working as contractual labourer some where. In most firms, medical expenses and LTC are covered for both the employee and and his dependents, and in case of larger organization also give its own rest houses at subsidized rates. IR does exactly the same, except that since its employees also run the organization, it is able to provide privilege passes for them. the other passes are duty passes, but they are needed for work purpose as regular inspection are part of their duty, along with FP inspections.
