Forced by the company to do on-call support on diwali.

Yes you heard it right. It's for a company where most ex-Byju's folks have joined by parasite takeover(You can Search in linkedin). Ex Byju's folks aren't asked to do on call during that week because as per the company only they have a fair share of rights (as their bosses present everywhere)and non-byju's folks don't have. I hope their Diwali will also get ruined sometime, who are doing this kind of discrimination.
