I just found out I will be laid off

What you should do is:

1) Get a lawyer and some legal advice on not giving you a contract.
2) Pretty much stop working very hard. Since you're out the door, why bust your ass?

Seriously, the fact that they're downsizing their business and not including you is a sign that they're expecting you to keep working your hardest to make their business run and then drop you like a bad habit. You already know when you're going to be let go. The only difference is if you're going to work as hard for them as you were or if you're just going to ride out the next three and a half months looking for another job. Fuck 'em. In this world, you look out for yourself. And if a business is stupid enough to expect you to bust your ass for them when they're pushing you towards the door, don't bother. Spend most of your days getting another job for after your June vacation.
