Dear Friend,
Kindly pose this question to HR personnel. Safety and related people may not be able to advise you on this. However, I can very well say that your anxiety is unwarranted. Experience anywhere is valuable at work and in life. Back here in India, your Gulf experience will definitely pay you rich dividends.
You worked in the Gulf for some time. You also worked with an MNC in India prior to that. Definitely, you have thus experienced the difference in working there and in India.
The most important difference is that in the Gulf, no excuses are entertained for unsatisfactory work. You have to do your job satisfactorily. They want you to do the job on your own. If you are found unfit, you are sacked. No one will come forward for your rescue. You have no grievances there - you just work. In the Gulf, there will not be anyone interested to heed your grievances, even if you have any. In India, you have more grievances than work. After confirmation, the majority of employees here talk of their employers as their worst enemies - I used to hear. There in the Gulf, you do not dare to go for unhealthy criticism against your employer.
Here you are paid by the employer, but you are loyal only to your union.
You work in the Gulf even on weekly holidays. National holidays are limited. Even for national holidays, the option is there for you to work and earn overtime, which you will never forgo. There is no bandh or hartal for you to enjoy every other day. You won't avail frequent casual leave, privilege leave, or sick leave. Probably in your service there, you never availed a sick leave. All because there you earn many folds for doing the same job.
My advice is "your experience will be valuable everywhere, but you consider options yourself and make decisions of your own."
Regards,
Kesava Pillai
