How to get release from toxic project, working in same project for more than 7 years.

They won't give !!

If thats the case Leave asap! Prioritise your mental health trust me saying from experience

Tell them you are putting papers, they will release as no one want their project to get disrespected by associate resignation on active assignment

Only way out is stop working !!

You can ask for release it's a tcs policy more than 3 years you can ask for release

After 3 years you can ask for it. If they are not giving then speak to HR
