C212,
No I am not. I used to work for Evergreen. There is a saying around the helicopter industry, 'Everyone has worked for Evergreen, ONCE'. The CASA's are under the helicopter program, so the FW pilots are treated like a lesser life form. There are some good people there, but the management resembles the movie 'Animal House'. The benefits are good. Keep in mind since you are working overseas, their insurance program kicks in immediately, not 90 days down the road. The pay is normally a little lower that the norm for these types of contracts. Evergreen has a history of paying under the average pay for the area and industry. Your job is only as secure as the contract. When the contract goes away, so does your job. While it is possible that they might continue to use you after the contract, it is not the norm.
Maintenance is normally good, but the final quality as always depends on the quality of the mechanics in the field. John K. was and most likely still is the the Director of Maintenance out of McMinnville. He has a very good head on this shoulders, but remember he is a company man, first and foremost. If you have a problem and he likes your suggestion on how to deal with it, he will support you fully. If he doesn't like it, don't go there.
It is like no other company you could imagine. You will go places and do things, you never though you would do. It is an experience you will never get anywhere else.
