WannaBeBiggles well said.
Using floats as the example, it is a notoriously difficult 'niche' within a dog eat dog industry.
I have heard of too many examples of people sending in resumes to operators stating that either 'Floats is my dream job and will work for free to get a foot in the door', or 'I don't have the training but have a CPL with 250 hours, if you provide the endorsement then I will work for free for 'X' months'
What people don't realise is that for many of us, flying is our only source of income i.e we need to work to pay the bills. We don't have the luxury of mummy or daddy's bank account.
For those who want to break into the industry (and not just floats) then sometimes you have to do the hard yards! Be a ground crew personnel, wash planes, be in the ops room.
Not only will it get you in a company, but it gives you a fantastic opportunity to start to network.
Remember it is a very small industry, so don't burn your bridges. And for f**k sake don't work for free!!!
