Steep wage hikes for union workers mark the 'final echo' of the inflation surge, Goldman Sachs says

• Wage increases for union workers don't signal a coming resurgence of inflation, Goldman Sachs said. 
• Recent strikes and reports of unions gaining more pay mark "the final echo of last year's inflation surge."
• Wage gains for unions come amid a tight labor market and sticky inflation.

Recent wage gains for unionized workers signal a lagging indicator for inflation that comes as the labor market is still tight and prices remain sticky, according to Goldman Sachs.
