You can crate-train him now - what this does is give him not a "penatly box" as you might think of it, but a "secure cave," where he has a nesting place. If he's got a stuffed toy, or something to chew on in there, it will help keep him occupied while he settles down.

What you can also do is NOT fuss over him when you get home, as this will just reinforce his anxious behavior. As hard as this will be, ignore him for several minutes when you get home, as if it's no big deal. Then, five minutes later, or once he's calm, you can initiate play time if you'd like.
