I think that you'll agree with me that no one can comply with your request because it lacks specificity. We do not know what your establishment is, a factory or a shop or a trade union or a contractor's establishment or a catering establishment etc. If your predominant work is that of compliance management under the labor laws mainly in respect of documentation, I hope you will have a basic idea about the prescription of filing of periodical returns exclusively under certain labor laws applicable to your establishment and its prime purpose.
Filling up of a return with a specific periodicity is nothing but the consolidation of the day-to-day compliance in respect of maintenance of registers, notices etc under the various labor laws connected with one another. Therefore, it would be better to avoid spoon-feeding in such matters involving compilation of statistics collected from various documents maintained in the establishment periodically. Be specific in your doubt.
