Have to agree with LC.
SIA Cargo is not for everyone. IMHO your happiness will depend on your hopes and expectations. That, in turn, is usually conditioned by where you are now.
If you join from a major European/US/Australian carrier, with a strong union and have a single digit seniority number, then stand by for a major culture shock. If you are coming from a second or third level carrier then it can be a step in the right direction.
Housing and Scheduling are 2 big issues. If you have more than 2 children of school age then so is education allowance.
Expat managers are ok but be prepared for the 'corporate culture' to treat you like tools in a tool box to be picked up and put down at the company's whim. Basic salary needs improving to be more competitive with the sand pit - to whom we are about to lose several high calibre Captains - and pay no notice to the summary of the terms and conditions which states that 'Housing Allowance will be reviewed if there are significant changes in the market." In the last 2 years typical rentals have gone up by over $3000 pcm and Housing Allowance has increased by only $350 pcm. And that only given grudgingly after a protracted battle. The Union appears powerless (or incentiveless) to look at things such as Housing Allowance.
Be prepared to subsidise your housing to the tune of at least $1000 pcm and to have to accept a reduced standard of living to keep the subsidy to that sort of level.
On the good side, the profit share (for now) mitigates against the low salary and you can get 5 years income tax at a flat rate of 10%.
If SIA Cargo wants to keep its current pilots the package needs improving significantly. Until then, for the majority, I think it will be a case of join, work out when you can afford to leave, then go.
Singapore as a place to live is ok for now, though there are plans to increase the population by 25% in the next decade. That will have its own effect on housing, education and general appeal as a place to live.
