Hi Arul, you have to obtain a separate license for each work or each PE. It's contract or WO specific, quantifying the number of persons required or to be deputed and the nature of the assignment.
Principal Employer (PE) Requirements
A 'Principal Employer' (PE) who employs twenty or more 'workmen' on any day of the preceding twelve months should mandatorily apply for CLRA registration to the Labour Department of their respective states, stating the maximum number of employees to be employed. They must obtain and issue Form 5 to the Contractor. There is a cap on the number of persons licensed as appearing in Form 5 issued by the PE. Also, the licenses so issued should be renewed periodically using the online portal.
License Renewal Process
Licenses issued by the labour department can be renewed online! Visit the website:
www.tn.labour.gov.in. Choose the option 'license renewal'. Fill up the details asked and submit. The license will be renewed.
