I think Klimax is trying to say that it's not a very good idea to adapt your entire life to a job with SAIL (moving your family, turning down other job opportunities etc.) It's a job, not a career... and may not last for that long. It's not like joining EZY or RYR where the company is opening up new bases every year and all employees consider new joiners at those bases as equals. You will not be welcomed by other SAS staff.
