Speaking as someone who has been laid off, there is no use worrying about it. If it's going to happen, it will regardless. I know it is somewhat stressful, but focus on the things you can control at work. And if the worst happens, there is life after Enbridge. I love my new job and moved on without regrets. It is just a job after all.
Wanted to reiterate what @QFhCXmz-1wzm said in another thread. Chances are no matter what happens, you'll be okay in the end. It might be tough for a while (my husband was laid off from his job few years ago and it took us about a year to bounce back,) but you'll recover usually sooner rather than later.
Protect your health, folks. Nothing is worth you ending up on medication or worse. Not even Enbridge.
