This is the same thing some are saying in Italy, on the “Reddito di cittadinanza”. There’s now a shortage of people willing to work in bars and hotels. First of all people that needed another work, when they lost the job, they searched another and found it. I personally know a former waiter that now works at a car mechanic. More pay, less hours, and free Sundays. And no screaming kids running under the tables. So I suppose other people did the same thing.
Another thing is that the norm on these place was proposing working off the books, that is of course illegal, and in this case people what were working illegally resulted really poor ad got eligible for “Reddito di cittadinanza”.
Offering a job with decent pay got a lot of people sending CV. Sammontana ice cream factory (google translate) (google translate link) was an example of this.
