I was once on a project which lasted about half a year. It was really tough work, in a foreign country, harsh conditions, bad management... People were nervous, and one day they found out someone had 12X their salary. It was me, but they didn't know it. I didn't know they didn't have same salary as me or close to it. I was brought in as a specialist, but even people higher than me had smaller salary than me (4X smaller). Situation was not great after that, but names were witheld. I always wonder how it would play out if they found out it was me, we were all on friendly basis.
