Kung 1 week ka pa lang, at di mo pa nacomplete ang pagbibigay ng requirements sa company at pagsusubmit ng govt forms,e better just email them then AWOL. It wont hurt your record unless your 6 months of contract has details of payment or bond to the company. This may opt company to complain you for a civil case or labor case.
Mas safe and legal, tender your resignation letter then yur intention to render 30 days notice. If mas mapapabilis ang approval ng boss mo ng last day mo, e relief na yung pangamba mo.
Bottomline- before joing a company, ask all your questions during job offer signing. Itanung mo na lahat, as in lahat!
