It is not a paid position; you will help load and unload the freight and possibly log the return leg so long as it is empty. Loading not a job it's something you do around your normal schedule. This is first hand info, I work there. I think the OP's question has been answered (if it hasn't feel free to ask or PM.) and I'd like to take this opportunity to hijack this thread.
A lot has been said about this place in the past few weeks and I'm not sure that all of it is completely accurate. I've read the other thread that Ollie linked and other times that Kamaka has been mentioned in the few years I've been on here. First of all the Beeches and Van are a single pilot operation. They can and do fly without a "loader" all the time. If no one wants to come in for the early flight we're loading and unloading the plane ourselves, lifting and dragging freight is part of our job description. Even with a loader we always bust our asses right along side them. As long as I've been here there has never been PFJ/T. Everyone has been hired out of the cadre of loaders.
Is this an ideal situation? Of course not. But loaders are not taking jobs from anyone, not even non-pilot loaders. The other 135-cargo outfits are either $13-25K PFT or aren't entry level. If you want to make a life here your options are sort of limited.
