This came as a surprise to easyJet pilots too. We are short of crews as well, cancelling many flights for this reason, so no idea why the company would consider this.
It might probably appeal to young, single guys wanting to "try" long haul, keeping the possibility to go back home after a reasonable amount of time.
Nobody in the country where I am based would even consider to leave easyJet to Emirates, with no possibility to return.
