Pros

Coworkers are amazing people. Interesting work.

Cons

Pay is very uncompetitive. Management is demanding, people work close to 9-10hrs per day. Company is not transparent about pay and performance. Bonuses are very small, raises are less than inflation. Performance and long hours are not rewarded.

Pros

-Work and life balance is good -Easy job -company pays for the Extended Health Insurance 100%

Cons

-Growth and development -Low salary increase -Management in production does not like production people to participate in company activities -They don’t care about stabilizing manpower especially if you are an assembler and high turnover rate. -Bonus depends on overall MKS performance so if one country did not perform well then bonus get screwed.
