Recently I cleared an interview and I accepted the job offer letter during this I discuss about salary points verbally with Head of HR. When I received offer letter by email, I read the whole letter and at the end they mentioned that the salary annexure and appointment letter will be issued when I'm joining.
I discussed my salary verbally with the head of HR and when I requested to update the offer letter and mentioned my expected salary point, they refused (they said due to their policy being to not disclose this) and said I will get the appointment letter including salary upon joining.
So is this offer letter legally correct or not?
