Hi Toshi,
Welcome to the forum and this is your first post ever since you have joined. :)
"Do IT and Manufacturing companies in India provide 'HARDSHIP ALLOWANCE' to their employees who are working in Remote Locations?"
Please explain what you mean by remote locations.
Is the place of posting temporary or permanent in nature?
Are amenities like schools, housing, and hospitals available?
Hardship allowance is generally not given as it becomes taxable. Instead, companies address issues like housing and buses for children for schooling. If you further clarify the above questions, my colleagues here can provide more information.
Have a great week ahead!
Regards,
Rajat Joshi
