I would be surprised at double digit unemployment by the end of the year, but it certainly isn't out of the realm of possibility.
I have always been expecting it to peak late summer, but they keep on pushing it back, so who knows. I was hoping for no higher than 9% by the end of the year, but I'm not sure I'm going to get that wish.
There are many jobs that take a huge hit during the colder weather. The sagging economy may force many of these companies to reduce the pay roll over the winter to keep their heads above water. With this in mind I expect to see an increase in job losses.
I would also guess that the seasonal holiday jobs are going to be less plentiful as folks scale back on their holiday plans.
