Domino's Pizza (NYSE: DPZ) is slated to report its results for its second quarter of fiscal 2022 before the market open on Thursday, July 21. These included staffing shortages, which constrained revenue growth, and sharply rising input cost and wage inflation, which took a bite out of the bottom line. The slowdown over the last two quarters, however, wasn't just due to these factors, but also to staffing shortages stemming from a tight labor market and the nationwide surge in COVID-19 omicron variant infections in late 2021 to early 2022.
