Work from home job

Unfortunately moonlighting / freelancing / part-time working / working from home, et al., are all strictly against the prescribed and seriously followed Omani Labour laws. So no company worth its salt would engage people in this manner.

But there are many small outfits / businesses / companies who would need help, but do not have the necessary bandwidth to appoint / employ the required resources. And they might engage people to work for them surreptitiously.

The biggest risk, besides of course the possibility of facing serious consequences if caught by the Ministry of Manpower, would be you may not get paid fairly, or on time, or even get paid at all for your time and efforts. That's because you cannot go and complain about this to any authorities, since you will be engaging in an illegal activity.

Good luck.
