Union work rules usually required cake and bread products to be delivered to a single retail location using two separate trucks. Drivers weren't allowed to load their own vehicles, and the workers who loaded bread weren't allowed to load cake. On most delivery routes, another "pull up" employee moved products from back rooms to shelves.

Economic effects of labor unions :

1) cause or perpetuate unemployment
2) cause artificial inequalities in wage rates if confined to isolated industries
3) combat rise in real wages in combating rise in productivity of labor
4) frustrate the law of comparative advantage and prevent the less able from outcompeting the more able
5) the greater the extent of wage increases achieved by labor unions, the more severe become the effects of minimum-wage laws
6) impair capital accumulation by reducing productivity of capital goods
7) monopolize the market against the less able and the disadvantaged
8) prevent increase in money and spending from increasing employment
9) promote racial discrimination
10) reduce average real wage rates by causing unemployment and a lower productivity of labor
11) reduce fraction of worlds money supply circulation in United States
12) responsible for inability of American industries to compete against foreign competitors
13) unemployment caused by labor unions worsens consequences of job loss
14) wage demands of labor unions can lead to more raid increases in quantity of fiat money if government seeks to avoid resulting unemployment by this means

That was the paragraph that jumped out at me, too. Two trucks from the same warehouse to go to the same store each day, by union rule. One for cake and one for bread.

Inefficiency, locked in.
