Note that the article doesn't contain the word "shortage". It's just the continuum of supply and demand: if people like the ones you hired last year can't be found this year, you have to pay more, or consider those you'd have overlooked, including felons. If they have a stronger bargaining position, they get a better deal.

Note that the article also doesn't contain the word "immigration". It deserves to be noted that the jobs being discussed here have a huge overlap with the jobs often filled by unskilled immigrants. Whatever your views on ex-cons and low-skill foreigners, I think it's important to understand that there is a trade-off between them.
