Two diametrically opposed quotes from the article:

"Employers find the H-2B program expensive and bureaucratic, and tend to reserve it for hard-to-fill jobs that are critical to expanding operations." (American Enterprise Institute for Public Policy, 2011)*

vs.

"In the Pentagoet’s case, that’s meant six women from Jamaica (about a fifth of the total staff) who work in housekeeping and in the kitchen."

Are housekeeping and kitchen jobs hard to fill, critical to expanding operations, and worth significant investment? I'm just confused about H1-B in general and what it's supposed to do. Bring high-skilled workers? Provide cheap, seasonal labor? Both?

*Paraphrased for readability. Original quote hedges the conclusion.
