This bill will only be signed by the President once an enrolled copy is sent to Malacaņang. Sending it is the job of the legislative so the Senators should not make an issue on the delayed signing.
Anyways, this bill is a good development for wage earners. In fairness to both Houses of Congress, they expedited the passage of this bill in time with the current events regarding world problems on rapid increase in oil price thus causing rapid inflation.
