Dear Panchal,
Whether it is a Private Limited, Partnership firm, or Proprietorship, the Gratuity Act will apply if they employ more than 10 members. The designation is not the issue. If anybody is receiving a fixed amount as a Consultant's salary, then they are not eligible for Gratuity if they have completed more than 5 years as a Consultant or Advisor, etc.
In other cases, with a designation as Consultant or any other designation, if they provide a salary slip or obtain a signature in the salary register showing Basic+DA+HRA+Conveyance, and the employee has completed more than 5 years, then they are eligible for Gratuity. For example, if the total service is 5 years 6 months and 10 days, the calculation of gratuity is for 6 years.
Regards,
