I'm in the US, and on a contract sure, as a contractor I was once told 7 weeks before that my contract was not being continued (new CIO put a freeze on all new hiring/contracts/contract extensions while they evaluated workload). That contract had already been extended twice. Also once, as an employee not a contractor, I was laid off and while I was given time to say some farewells to colleagues I was politely asked not to attempt to log in. I had worked there long enough that I received 6 months severance pay so I had time to get another job. FWIW, All of my career has been in the American mid-west in "employment at will" states. I've never been asked to sign a contract as an normal employee.
