That would be a 26.13% layoff. The first layoff left you with 89%. Of that 89%, you lost another 83%. 0.89 * 0.83 = 0.7387. 1 - 0.7387 is how much you lost = 0.2613 = 26.13%. It's probably clearer to reason about if you have two consecutive 50% layoffs. Clearly you didn't have a 100% layoff. Your workforce got cut in half twice, leaving you with 25% of what you had originally (or a 75% layoff).
