It is no secret that Aramco was a better and more professional environment when expats (the competent ones) were holding management positions at all levels. I believe the mistrust between Saudis and expacts, for the most part, surfaced after too many expats were hired in 2008 and the years after including a lot who are by any standard below average. Some of those below average expats are posting offensive comments here.
It is probably true that the company is sinking for two main reasons:
Not allowing highly qualified expats to hold management positions. Those can "make Aramco great again"
A good number of expats with poor performance receiving 3 or 4 times the salaries competent Saudis receive while both have the same job title and responsibilities.
Bottom line is, if you are just selling your time here, pack your stuff and start looking for a job in another company before you receive your 60-day notice.
