Thanks to our niece Emma for submitting our papers to the Korean Embassy and for claiming our Visa. We are 9 in a group , 7 are employed and 2 business owners. All of us were approved. In our experience its not really difficult to get Korean Visa if you have complete papers. Also, we had an invitation from a Korean (wife of our nephew), for their wedding in Korea. This also add to our papers which I think add merits to our qualification as tourist in Korea.
Here are some tips in getting visa in South Korea, this is based on our experience. Visa Requirement for employed and businessman 
What we observed
1.Korean Embassy is not strict as to the amount of money you have in a bank. I only have 50k ph pesos outstanding balance and my average daily balance is only 20k. Its my payroll acct, money comes and go quickly
2 Review all the papers before submitting. Two of our companion’s paper were returned because the Certificate of employment does not include the landline number of the employer and the other one submitted an Income Tax Return which is not a year immediately preceeding the date of filing for Visa .
3. Go to the Korean Embassy early before 8 am , many Filipinos love to travel to Korea specially the young, maybe an influence of Korean Novela being aired in the Philippines
4. Be aware of Korean Holidays , their embassy is close These are the holidays in SoKor
We realise that what you need to prove is that you dont have a reason to overstay in SouthKorea or to reside illegally because you are gainfully employed or has a business that is doing good in the Philippines By the way the Visa is free if your travel is less than 60 days. We avail of the promo ticket even without the visa yet
