"Asshole" isn't the right word, assuming you mean they are working overtime regularly without pay. I'd probably use other words like "gullible" and "useful idiot[1]." And, yes, I would put them in the same tent as the other useful idiots who'd happily (as opppsed to out of desperation) take a job advertised as per the link in the article.
