How Should I Communicate Notice Period Changes to Employees Effectively?

Our company wants to change the notice period for both probationary and confirmed employees. I need to issue letters to employees regarding the change in the notice period. Could you please suggest the best format for this?

Please clarify the current notice period duration and indicate whether you would like to extend or shorten it.

Currently, we do not have any notice period during probation, which is proposed to be changed to a one-month notice for probationary employees and a six-month notice for confirmed staff. However, we aim to reduce this notice period to three months.
