"I WORKED AT WWOR-TV BACK IN MARCH 1981 THROUGH OCTOBER 1981, WHEN THEIR STUDIOS WERE IN TIMES SQUARE AND WAS REQUIRED TO JOIN IATSE. WOULD THAT MAKE ME STILL A MEMBER...????"
Good question. The short answer is No. Sometime after you moved on to better things the engineers at WWOR decertified IATSE and went with NABET.
When Fox purchased WWOR the engineers there were moved into the Fox5 IATSE local, because the IATSE Local 794 contract was the better of the two.
The good news is IATSE would be happy to have you back if you go to work in one of their shops and it is possible that they would deduct the initiation fee you originally paid from the current fee.
All the best,
