The management of every place has its personal preferences, not based on efficiency. We once knew a manager who was so distressed by impediments of speech that he could not endure persons with these peculiarities in his organization, although their manner of speech had nothing to do with the quality of their work. Every manager has some more or less marked idiosyncrasies, and these must be known and studied by prospective employees. The personality of the management and its effect upon the worker under its direction and leadership are other important factors. The manager who is a keen, positive driver will get good results with a certain type of people in his organization, but only with a certain type. The efficiency of every man in the organization is also conditioned very largely upon the personal preferences, personality, and methods of his immediate superior--his foreman, gang-boss, or chief. Certain types of men harmonize and work well together. Other types are antagonistic and discordant. By their very nature they cannot work in the harmony which is essential to efficiency. In making choice of work, the man with good judgment scrutinizes all these important elements. ASSOCIATES AND SOCIAL ADVANTAGES Every vocation has its social environment. There are fellow employees, or professional associates, inevitable in the work itself; also the particular class of society fixed by locality, income, or the standing of the vocation. This chart may seem, at first sight, to be complex. It must necessarily be so, since it is arranged to cover all professions and trades and all industrial and commercial positions, from the presidency of a corporation, general managership of a railroad, sales management of a factory, or cashiership of a bank, as well as less exalted jobs, down to those requiring little, if anything, more than brute strength. Obviously, not all of these facts need to be considered by every aspirant, but only those which have a bearing upon his particular case. The tendency, however, is to neglect important factors rather than to waste time over those which are unimportant. PERSONAL ELEMENTS OF THE PROBLEM Having determined, in the manner indicated, the standards of work and of the environment, the man is ready to examine himself to determine where he fits. There are six headings under which he may classify the various items of information needed in fitting himself to work and environment. These are health, character, intelligence, disposition to industry, natural aptitudes, and experience, as shown in Chart 3. This chart does not, of course, present a complete and detailed list, but it is suggestive.[2] It would not be true to say that any one of these is absolutely more important than the other. They are all important. Their relative importance may be determined by the vocation to be considered. [Footnote 2: See more detailed lists in appendix.] HEALTH
