It’s flat out against the law to replace an American worker with an H1B worker.

How do they get away with this ?

I bet they hired Cognizant as a "managed services" company. The entire operation is turned over to Cognizant, including people. What Cognizant does with them is of no concern to the Company.
That is how they get away with it.

How do they get away with this?

By outsourcing the functions to a separate company. That way they aren't firing an American worker and replacing him with an H-1B. They are firing the worker because the position isn't there anymore. It's with the outsourcing company, who can hire whoever they want.
