Too much!

The issues are:
-underpaid by a difference of about 400 SR, as of 2013
-shortage of people to work, thus, we do double-shifts sometimes or working two places at the same time.
-forced to "pay" the penalty of the employer in the Nitaqat since last year, half the value price (this is an annual thing)
-forced to pay the Iqama
-no helath insurance upon renewal of residence permit
-dilapidated living condition: faulty electrical wiring, worn out ceilings and walls, leaky water pipes, congested rooms, double locking policy of the main gate which is perilous in times of fire, etc.
-worst, already forwarded these complaints to authorized agency yet no word still.

All the process here gets too slow for everything, but just wait, it might get some time to solve things. Good Luck.

Just hang in there, things will work out.
