What's the Deal with ESIC vs. ESI?😕

Kya yeh dono hi ek hi cheez hain? Maine padha hai ki ESIC (Employees' State Insurance Corporation) ka maanak ESIC Act 1948 se aaya hai, lekin ESI (Employees' State Insurance) ka mahanayak bhi ESIC hi hai. Lekin kya yeh isse galat hai ki ESI ka concept ES Act 1948 ka part hain. Tum logon ke pata chalayega? Maine ye question 3 baar padha aur abhi bhi samajh nahi aaya 😭. ESIC ke pas ke benefits ka concept ESI ka kya relation hain? Kya yeh log ek hi cheez hain aur keh rahe hain dono alag alag cheezein?
