How To Terminate An Employee With Behaviour Problems.

First of all please try to know the reason she was not taking her job seriously if she tells that well and good.
If you want to give her a chance than give her written warning that you are increasing her probation period due to ......... reason.
And if you don't want to give her a chance and have a better candidate so you can terminate her job by giveing her written explanation.

After going though this case...
Technically Mr Manjunath's comment seems appropriate. But still I feel, Human resource is very important, crucial & delicate factor to handle in company. Human is not object or thing which you can throw like waste. Every person has unique ability. You have to judge & use intelligently smartly for betterment of your company.
I think, she need appreciation.Coz,Appreciation is basic need of emotions which leads to improve efficiency & enthusiasm.
See as you appointed her in your firm, that means you saw some spark, eligibility & ability in her to work with your company. As she is new in your company, she need time to cope-up with company's environment.
This is my opinion based on information received on this page.
I can change employee's behavior if you consult me in-person.
