I bet they don't pay $100k for a 300 hour electrician.
They're also looking for an experienced guy.
There is a shortage in general of experienced people, not only in aviation.
But the fact a helicopter pilot runs a lot more risk than in most other jobs, including fixed-wing pilots, the pay should be accordingly.
This however can only be achieved by the pilots and don't expect employers just to raise the wages. But most of us just jump on a job without negotiations. Yes you should negotiate beffore you start. As soon as you started working you can forget it, don't expect anybody start paying you better when you perform well. An employer just takes that for granted and after all he's paying you to do the job well, so nothing you have nothing to complain about.
But in general off course I think the pay is to low, don't get me wrong.
