Hello Biju Dash,
First of all welcome to Orissaspider and regarding your question I would like to say that, now a days employment is a great challenge for unemployed youth so it will be better if you will continue this job till getting a good and secured job.
And MBA is getting very much popularity. If you will do MBA in part time then sure you will get a better job than it and if you will leave this job then you can do MBA as full time. Now Sambalpur University, Berhampur University, Utkal University, Sikkim-Manipal University and many more are offering MBA part time degrees. You should choose the best among them.
