Does the card require that sufficient resources be available in the port warehouse or on-hand treasury to work, or will it give a relative boost to the number of workers affected.

For example, If I have 100k workers and I only have 5k food, I assume that the 25% boost will apply to the 50K workers and that my relative health for all workers will increase by 12.5%
