Just so we’re clear, there is no cancelling/not renewing of E3 visas.
You cannot subvert the contract for the sake of getting rid of people via other means. Seniority still rules.
You must be treated as if you were a citizen/green card holder/any other employee. If a company tried to use the renewal of an E3 visa against you, they’d immediately be subject to unfair dismissal (or whatever its equivalent in USA land is called) without question. It is very clear in the E3 paperwork you sign with homeland security or whomever sends it, it is a lot of legalese in there but it’s all very important. You are not a sub set, lower tier of worker, you are not a temporary gap fix, a casual worker to deal with the ebbs and flows, you are not a migrant popping in. You are full time annd typically paying union dues. Aside from your ability to permanently reside in the country you are identical to everyone else on the list. That is it.
Feel free to message me if you wanna know more of how it actually works, I’m living it right now.
Just stop with this bs “E3’s mightn’t be renewed” mania. This isn’t Australia with their temporary workers rights or 457 visas which can be revoked willy nilly.
