We have heard of these workforce shortages many times since already a couple of months into the war.
The Russian economy is kind if overheating due to huge public investments in the war effort.
At the same time Russia is losing workers because people are fleeing Russia and continued conscription to the military.
The difference is they now say the shortage is 42% whatever that means? But it sounds very high if true.
Ironically the Russian economy is in a recession at the same time it's overheating. Meaning that when the card-house collapses, it will probably collapse hard. This will probably happen when the war chest Putin built is empty, and they've used more than half already.
If reports such as these are correct, I doubt Russia can keep this up for another year.
