Depending on which state or province you get laid off (since this is basically the situation in Canada as well), you're entitled to some severance pay. I got laid off from a large multinational IT company after a couple years working there in a junior role, and I got less than 20% of my annual salary as a severance, which my employment lawyer told me was within the upper range for someone of my experience and seniority working there.

As for warnings though, it's rare that people are given much, especially when it comes to larger companies. I was taken aside to a meeting room, was announced by my manager that I was made redundant, was introduced to a guidance counselor for the agency the company had retained for me, my personal belongings were brought to me from my desk, and I was shown the door. I didn't get to say bye to my coworkers. It's pretty harsh.
