NJ deductions for GA resident

My NJ-based employer withheld NJ FLI, SDI, and UI/HC/WF. I have lived in GA for the last 20 years (never in NJ, no plans to move) -- I'm a remote employee from the start. Is there any way to recoup this money? It sure adds up, and as a GA resident paying GA taxes - I'm not even eligible for these services. My employer insists they are correct in making these deductions; is there any recourse?
