Hi Rajat, See i can understand what you are going thru but my dear we you know that company has a rule to server notice of 3 months before leaving and you have agreed on employement terms while joining them, you have to spend your time there..also i can understand that the work pressure and thier behaviour is bothering you but seriously this is the geuine reason that you mentioned here that you are leaving this organization of their bad work culture or not suitable to you...
Yaar you must need to understand that culture of any organisation/company can be according to you and your style and you have to adjust yourself..and please let me know the other reasons for your ths decision bcz i dont think that one can leave his/her job bcz of culture..and what kind of culture you are talking about...what you have seen there...can you please explain????
Second, have you applied for job somewhere else or have any offer...we all know that we shud not take this kind of action in our life just bcz of this culture problem bcz every industry/company has their own culture and work style...IT industry hav their own style and culture and a Mnufacturing company have their own...if you'd ask me i can tell you about the Retain, Engineering, Manufacturing and Garment industry too bcz in my long but short career have worked with them and seen their different culture and style of work but i dont think this, your this decision of leaving you current job bcz of culture problem is right...
Anyway if you really dont wanna continue your job or have another options in your had, have to spend your time bcz until then they will give you exit clearance and your salary of this period and experiece certificate cant be offered to you....my advice is that you need to ask your Boss again and tell him/her that you have to go early with a valid reason and can request to relave you .....thts the only and simple way to tackle your problem otherwise you have to spend your time, have to serve your notice...
