Yes they do, quite a lot of them actually. Getting your foot in is very, very difficult if you are not properly connected or plain lucky.
One route is to start on the ramp as a loader, then work your way to load controller. With loads of experience, you can then start firing off applications. A couple of years on the ramp and ditto in load control would probably be min. required.
Then comes the difficult bit, getting a foothold with an airline that does indeed employ loadies. I guess here is a classic case of "it's who you know that counts". As long as we fly to dodgy places and carry odd-siezed loads, there will always be a requirement for loadmasters.
The airforce route is another option.
