Your salary should be based on industry norms. Are you earning in dollars or in Dhs in Dubai? If in Dhs - Most companies will use a cost of living formula (HR stuff) to convert your current earnings to a Dhs equivalent - this doesnt mean that you just use the excahange rate. in fact you cant compare your current earnings to your package in Dubai (especially if you earn in sterling or dollar). Ask your HR team to provide you with the breakdown of the company/industry norms, some companies have stated entry and ceiling levels by job, by level, by expat country of origin
