Awol while rendering resignation

Hi po. Nagpasa po ako ng reaignation letter april 5 this yr with effectivity date of april 15. I already rendering the remaining days. Then for the last 2 days umabsent ako, Nagadvise naman po ako sa supervisor ko na Emergency Leave ko un. And ndi xa pumayag dahil kulang sila sa tao. I told her na di na talaga ako makkapasok. Kakausapin ko na lang boss namin. Then sabi nia ndi daw ako bibigyan ng exit clearnce ang ipapablocklist ako sa pass control sa airport since nagttrabaho po ako sa groundhandling agency ng airline. Hindi ako pinayagan magvacation leave dahil kulang sila sa manpower. Di ko nagamit ang vacation leave with pay ko. Nagresign na po ako. Dahil sa di ko na gusto ang pamamalakad nila. Tama po na na di akp bigyan ng clearance dahil lang dun?

In relation to this question.. I also filed my resignation dated Mar 27,2013 but since my manager was on emergency leave i submnitted the letter to our HR manager.. but since wlang pirma yung manager ko she did not signed the letter..

The content of my resignation lette is that may effectivity date is on April 25, 2013.. becoz my start date with my new company is on Apr 29, 2013..

So mar 28 and 29 is a holiday kaya di rin napirmahan ng manager ko yung letter ko.. come April 1, 2013 di sya pumasok.. Apr 2, 2013 nag one-on-one meeting kme wiht my manager pero di niya pinirmahan yung letter ko kase nga daw di acceptable yung date na nilagay...

But since Apr 25, 2013 (thur) supposed to be is my last day...para lng mapirmahan yung resignation letter ko... binago ko yung content... i eliminated yung effectivity date without changing the Mar 27, 2013 w/c is the date when i compose the old letter.. tpos pinirmahan nya ang nilagay po niyang recvd date is apr 26... ngyn binabalikan ako less than 30 days daw yung resignation ko... may grounds po ba sila para kasuhan po ako?..Please help po
