Thanks for the replies.
I pick up my Record of Employment document along with last week's pay tomorrow afternoon. The manager also agreed to write me a reference letter since this isn't a termination due to poor performance or whatever. I am also allowed full access to the group heath insurance benefits until the layoff expires.
I refuse to enter the building and answer all kinds of questions from coworkers, so the manager agreed to come outside to give me the items.
I'm still bitter, but I feel better today.
