The paper only mentions total compensation as: "total compensation (base wages plus bonuses)"
Total compensation includes stock options, stock grants, health insurance premiums, 401k contributions, so-called "employer social security contributions", retirement contributions, time off with pay, etc. Total compensation averages 146% of wages.
This is not a triviality.
The paper doesn't cover this, and so the conclusions don't have merit.
Nothing you include in "total compensation" is guaranteed by employment.
There are also some fairly interesting trends in labor productivity.
Labor Productivity for Manufacturing: Household and Institutional Furniture and Kitchen Cabinet Manufacturing: (has flattened out in the last decade-ish)

Construction has been DOWN for decades (and is 7 percent of the labor force).

Food Manufacturing is in decline as well:
Health insurance premium subsidies being the big one. 90% of US workers probably are not getting any or any increase in the other ones.
Riding the boom times doesn't have merit either.
