How to Update Appointment Terms with an Increment Letter in a 7-Year-Old Company?

Hi, our company is 7 years old. Lots of appointment terms have changed. Can I add a new appointment with an increment letter, or is there any other way to give them new terms? I need an increment letter format that includes changes in terms and conditions in the appointment.

Hi,

I suggest issuing the revised terms of appointment as a separate document and not combining it with the increment letter. In the revised terms of appointment, you should reference the previous appointment letter by stating, "With further reference to the letter of appointment dated __________."

In the case of workers or employees who do not have reportees under them, any change in service condition should be implemented only after giving 21 days' notice as per Section 9A of the ID Act. However, in the case of those who have reportees under them, you can change the service conditions on mutual agreement.
