Your wicking problem is probably due to your work uniform that don't allow moisture to go anywhere easily.
You should probably not ride with your work uniform but rather use a jacket and pants with a windproof front panel to allow moisture to be expelled from your back then put your work uniform once there.

Here are some info:
