The number isn't inflation adjusted. The increase is 2.8, inflation was 2.9.. and the BLS has constant dollar version of this same report, and it indicates pay decreased by -0.1%.

WSJ decided to run with the non-inflation adjusted numbers, and then wrote an entire article saying workers got a pay increase... which they didn't. This is cherry picking at its finest. I'm actually flagging this.
