Dear Premkumar,
It is mandatory to have the license since these cranes/forklifts require special skills to be operated, and if used incorrectly, they can cause significant damage as well as harm to the working employees.
Today, in many manufacturing companies, the crane and forklift operators are mostly provided by third parties or contractors. Due to a shortage of manpower, contractors sometimes hire individuals without a license and provide training, but they instruct the drivers to obtain the license promptly.
However, in case of any accidents, the employees are covered under ESI, and an investigation will be conducted by the company. If a fatality occurs, the principal employer is responsible for compensating the employee's family, and the costs may be recovered from the contractors.
It is the responsibility of the Contract Cell/HR, contractors, and principal employers to ensure that only valid license holders drive the vehicles.
