So,Why do most of the employers here in Cebu and of the other regions opt for a no increase on the wage rate?

With regards to the title, the reason why most of the employers would not want a wage increase is because they see this as an increase, on their part, of expense.  Increasing the employees wages would increase their cost and lessen their profit. 

Yes, of course, increasing the wage of your employees is indeed a cost. An expense. However, what these employers do not see is that by increasing  the wages of their employees they are actually increasing the purchasing power of the latter. That by increasing the latter's wages, they can buy not only their basic needs but also of their children and etc. That these employees could possibly purchases their own employers products. And that these employees could possibly purchase not only their basic needs but could also afford other luxuries.

With all the economic crisis they say- although I don't think I could see that much here in Cebu since it seems that many are buying lands, cars and other luxuries-  and the rising prices of the commodities, I think that its about time that these employers increase the wage rate or else face the risk of having a rapid turnover of employees, although I can hardly imagine such thing happening  since there are a lot of unemployed people not only in this region, Region 7- Central Visayas,  of the Philippines but also the rest of the country.
