Pros
Working in the front offices at the countries is definitely I enjoyed for over a year back in 2007 and for a short period again back in 2013. However, working in their Shared Service Centre in Manila has been probably one of the toughest things I've had to do work-wise. Totally different with regards to the offices in each country: environment, teamwork, compensation and many other aspects are completely embarrassing when compared to their counterparts in the local offices
Cons
Aside from the mentioned above, unfortunately Philippines currently has one of the highest tax rates in Asia (and the world for that matter) at a ridiculous 32% on personal income. To that, you have to consider the 12% charged on every single product you buy and sometimes and additional 10% for other services (entertainment, etc), You definitely have to make a good deal before you sign your contract since the annual increases range from a merger 6% to (in the best of cases) a 12%. If you didn't negotiate a good entry salary since the beginning, you will have a hard time year after year seeing how others are making a whole lot more money than you do and probable working far less than you do.
