CHC isn't a bed of roses but it's a good company to work for. The benefits are some of the best I've ever seen. The pay is on par in Australia as the rest of the countries operators.
I don't know the details of the OPs position but I can't see it paying as well as a PIC or LAME. There are a lot of extra pay for endorsements and licensing applicable to the fleet.
CHC is a touring company so don't expect any special considerations for touring. They don't care how much time you spend away from home. Also if its 14 days on 14 days off its more like 16 days on 12 days off when you consider travel days and time. I know a lot of guys who turn off their phones and never check their email on there time off to make sure they even get there regular time off.
