Unemployment is almost always a lagging indicator of economic growth.
It's not just lagging, it takes longer and longer to recover.
The amount of time for the jobs to recover in recessions since the Great Depression has followed the pattern where the last 4 recessions took the longest, and in that order.
This current recession will clearly be the longest.
The 2001 recession was the second longest at 46 months
The 1990 recession was the third longest at 30 months
The 1981 recession was the fourth longest at 27 months
