Need an opinion pls

Dear Sirs,
May i ask for your legal opinion on this situation:
I was given a side agreement (notwithstanding our previous CBA 2004) and since this CBA has been scrapped last year due to non-availability of majority of union members (Union dissolved), would it be correct to approach the Management that i would like to collect my separation pay from the company inasmuch as the CBA has been succeeded by company policy effective this year?
Though i have a black and white agreement that my separation/retirement pay will be based on the 2004 CBA, my predicament is that since a new Gen Manager will be assigned every 3 years, will it be my problem na nababale wala ang kasunduan ko with the previous GM? or by-law, the new GM should follow what has been signed by the previous GM?
Thank you and hoping to receive comments/recommendations on what i have to do.

in my opinion, the new GM should respect the agreement. it is between you and the company, not between you and the GM.

Thanks AttyLLL for your prompt reply.
More power

Atty can i raise a question?
if i pursue the idea of retirement now and sign a quitclaim, it means i have to retire from the company, right? I am hesitant to raise this to the Management because on the other hand i wanted to continue my employment, but for reason that they scrap already the CBA hence, i wanted that i be paid the benefits as per the old CBA.
In your opinion, however, they have to respect the agreement between the previous GM and me.... thanks again [justify]

yes, if you retire, you will be separated from the company.
