Dear Khun Acharat,
I have been told by both Khun Yong & Kowit, that after they informed you that when they rejoined the Company they were promised continuity of Service that your advice was that i should take this matter up directly with Khun Vithit.
I do not see this as my job but rather it is your responsibility being in charge of the Group HR to ensure that the correct payment terms are given to staff that are in effect being terminated.
I am prepared to provide you with the background to their situation.
1) I informed the staff that i had resigned from the Company and both Kowit and Yong resigned and started new jobs, After being told that my personal issues would be resolved by K Vithit I agreed to stay @ YMC. I managed to persuade them to come back to the Company by promising them future job security and continuation of service.
2)I have informed K Vithit of this during meetings in the presence of David Howard.
I hope that this information allows you to pay them the correct amount of termination compensation
Best regards
