"Your service was always important for our business.. And now we think you have served our purpose!"
This is how they kick you out in smarter and sweeter way. On one hand, they are considering your service as an important factor for their business growth. But on another hand, they are showing your exit door because their purpose has been met. They have taken best out of you and now they think that you're no more productive for them. How cruel! But this the reality of world. Everyone is out their with you because you are somehow beneficial to them but when they realize that you are not worth it, they literally throw you.
