If you need to work hard, a jacket with some sort of waterproof laminate isn't going to cut it. A softshell is probably your best bet.

If you need to worry about rain, the best two options are a rain cape or a waterproof jacket with lots of pits and openings. I've used capes in the past. They work pretty well as you can sweat freely underneath it. I've also owned a waterproof jacket with lots of pits (a burley) and it was a trooper for many years.
