As my personal experience company outsourced me to a client and never backed me in case of any injustice from client. when I asked them to change my project they put me on bench and that too without pay. After staying on forced leave of without pay for one month, they forced me put down my resignation and that too without any compensation(as it was mentioned in my contract).
Also they never pay annual APDP amount even the company doing good , which is at least 20% of your ctc. (APDP contains individual performance + team performance+ company performance, and if all are doing exceptionally good then only you get 70% of the APDP amount ) .
