standing order is a legal format where as employment manual is only a guideline which has no legal sanction

standing order previls over the employment manual, if any difference between standing order and employment manuals standing order is final.

This makes clear for industrial establishments. How then establishments covered under Shop Act (eg corporate offices, software companies etc) are regulated in terms of standing orders? Also i have heard that in some states like Maharashtra,  even establishments covered under shop act must have their standing orders as per Standing order act ? Is it true ?.

if yes, then why many corporate offices have 'employment handbooks' instead of Standing Orders?
