About Change In Notice Period

Dear,
I have a query, Hope you can solve it.
In my company they have changed the official notice period which was one month and have made it to 2 months, This was informed the employee via Email.
Can a company change the notice period via mail.:?:
Should it discuss with the employees before sending a mail or declaration abt change in notice period:?:
About this in appointment letter it has no clause.:confused:
Help me.

Hi Sunilkhai,

Since there is no reference to the notice period in the appointment letter and since it is a sensitive issue which should not taken up through the e-mails as it can be disputed if an ex- employee decides to contest the same in the Court which are generally have a liberal attitude towards them in the cases of Employees v/s Management!.

The Management should give the individual letters and take the reference of their respective appointment letter in terms of date of issue or code if given and state the change of the above terms on the notice period.

These letters should be received and acknowledged by the employees and kept in their personnel files.

Regards,
