My view is that this just reflects short-term effects: people do not want to take jobs that pose infection risks. However, with the rollout of vaccinations in North America, this effect will fade. I do think there is some sectoral tightness that might cause an upward bump in wages, but I would be cautious about over-reacting to that. Since I am not in the business of short-term data forecasting, I am not in the position to dig into this. Even if I were, my bias would be that these effects will fade, so there is no point extrapolating the trends of a few months in 2021 out for multiple years.
