Hi There Sayyed,
Thank you very much for the effort put to develop the document you have provided “Appointment letter’ however I suggest you change it from Appointment letter to Service Contract. An appointment letter is only one page and contains the following information
•Confirmation of candidate’s acceptance of offer
•Position name
•Department
•Candidate name
•Grade offered & Accepted
•Basic Salary & Allowances Agreed
•Total No of Annual Leave entitled
•Benefits of the Grade
•Contract start & End Date
•Attached Job Description
That’s All
