Congratulations one getting your job!
Is the earning you mentioned for the entire month? Or is it your first job? If you are earning this much amount and still working for 2-3 hours a day at your first job, then it's completely okay to begin with because experience and skills are required at first. But you need to look for better jobs with better pay once you are skilled and experienced as this much remuneration might indicate exploitation of labour.
Hope it helps!
