32. Managing Workers “It is a reciprocal relation -- the boss is the partner of his worker, the worker is partner of his boss. Both are indispensable.” -- MLAW p. 117

33. Paying for Good Employees “One frequently hears that wages have to be cut because of competition, but competition is never really met by lowering wages. The only way to get a low-cost product is to pay a high price for a high grade of human service and to see to it through management that you get that service.” T&T p. 43

34. Mindless Work “Repetitive Labour -- the doing of one thing over and over again and always in the same way -- is a terrifying prospect to a certain kind of mind. It is terrifying to me. I could not possibly do the same thing day in and day out, but to other minds, perhaps I might say to the majority of minds, repetitive operations hold no terrors. In fact, to some types of mind thought is absolutely appalling. To them the ideal job is one where their creative instinct need not be expressed.” MLAW p. 103

35. Mindless Work When you come right down to it, most jobs are repetitive. A business man has a routine that he follows with great exactness; the work of a bank president is nearly all routine; the work of under officers and clerks in a bank is purely routine. Indeed, for most purposes and most people, it is necessary to establish something in the way of a routine and to make most motions purely repetitive - - otherwise the individual will not get enough done to be able to live off his own exertions. -- MLAW pp 103-4.

37. 1. Product Flow “If transportation were perfect and an even flow of materials could be assured, it would not be necessary to carry any stock whatsoever. The carloads of raw materials would arrive on schedule and in the planned order and amounts, and go from the railway cars into production.”

38. 2. Inventory “…having a stock of raw material or finished goods in excess of requirements is a waste-- which, like every other waste, turns up in high prices and low wages. … We do not own or use a single warehouse! How we do this will be explained later in this chapter, but the point now is to direct thought to the time factor in service.”

39. 3. Volume Buying “We have found in buying materials that it is not worth while to buy for other than immediate needs. We buy only enough to fit into the plan of production, taking into consideration the state of transportation at the time. But we learned long ago never to buy ahead for speculative purposes…we have found that thus buying ahead does not pay. It is entering into a guessing contest. It is not business. … the gains on one purchase will be offset by the losses on another … in the end speculation will kill any manufacturer.

40. 4. Flexibility “We believe … that no factory is large enough to make two kinds of products. Our organization is not large enough to make two kinds of motor cars under the same roof.”

41. 5. Standardization “Only six years ago, we used around six hundred different size boxes and crates for shipping. We studied the shipments and the boxes, and today, instead of six hundred sizes, we have fourteen sizes, for each of which a standard method of packing has been devised.”
