From what I know about tv shows ,channel has total control on actors. Sometimes even the payment of actors with high charges is directly remunerated by channel. Actors make direct contract with channel. I know few personally and so I know.
And this seems to be true. As komal said ved ji has been quoted. In fact at times even I wonder at the number of assignments kanikaa takes up.
I was very close to a new comer actress in the last show I watched and for her even a day off was difficult.
Kanikaa went to korea ,then lonawalaa ,then her promotions of restaurants ,exams . All this must have taken lots of time nd it must have been terribly hectic for her. For a FL of a daily soap ,who is there in almost every shot its difficult to manage.
So this article has truth behind it. But iy must have been sorted out as vedji said.
