(3.) #The Constancy or Inconstancy of Employment.# When a man is sure of being employed and paid regularly all the year round, he is usually willing on that account to accept a less rate of wages. Thus, there is little difficulty in finding men to be policemen at about 25 shillings a week; for though they have to go on duty at night, and their work is often tedious and disagreeable, yet policemen are nearly sure to have employment as long as they behave well. A carpenter or bricklayer, on the contrary, is sometimes thrown out of work, and becomes anxious as to the means of keeping his family. Masons and bricklayers, who cannot work during frosty weather, ought of course to have higher wages during the rest of the year, so as to make up a good average. Dock-labourers, who are simply strong men without any particular skill, earn large wages when trade is brisk and many ships come into the docks; at other times, when trade is slack, or when contrary winds keep ships out of port, they often fall into destitution through want of employment. (4.) #The Small or Great Trust which must be reposed in those who exercise the Employments.# This circumstance considerably affects the supply of people suitable for certain occupations. A man cannot expect to get employment in a bank, or in a jeweller's shop, unless he has a good character. Nothing is more difficult than for a person convicted of dishonesty to find desirable employment. Thus, a good character is often worth a great deal of money. Honesty, indeed, is so far common that it does not alone command high wages; but it is one requisite. The cleverest man would never be made the manager of a large business, if there was reason to think that he had committed fraud. (5.) Lastly, #The Probability or Improbability of Success in Employments greatly affects the Wages of those who succeed#. In some cases, a man can hardly avoid succeeding; if he once enlists, he is made into a soldier whether he likes it or not. Almost all, too, who become clerks in banks, counting-houses, or public offices, can succeed in doing some of the work required in such offices. Accordingly clerks are seldom highly paid. But of those who become barristers, only a few have the peculiar knowledge, tact, and skill required to make them successful; these few make very large gains, and the unsuccessful men have to seek for other employments.
