=13. Job Time Cards.= A method of time keeping which is an advance over the daily time card, is the use of a separate card for each job. With this method, accuracy of the records can be practically insured and the employe relieved of much of the clerical labor. To attain satisfactory results, it is necessary to operate this system along somewhat different lines than that described for the daily time card system. Instead of issuing cards for the entire day, the workman should be given a new card with each new job on which he works, and not until he has completed the job last worked on. The time must be recorded and the card turned in to the foreman on completion of each job. It is the duty of the foreman to keep his men supplied with work, and to have at all times a job ahead. The workmen, knowing that a record of his time on each job is kept and compared with the clock record, will naturally insist on having a new job card when each old one is turned in. If no job is ready, it will be necessary for the foreman to issue an _idle_ or _non─productive_ card──a condition which he will strive to avoid──all such time becoming a direct expense charge against his department. [Illustration: Fig. 14. Job Card Showing Names of Operations] To relieve the employe of clerical labor, a card, similar in form to Fig. 13, is used with quite satisfactory results. The special feature of this card is the provision made for obtaining a record of time. Below the heading there is a form representing the time of day, each hour being divided into ten minute periods, and the whole divided between forenoon and afternoon. When a new job is started, the workman makes the record by checking the time in the proper space. On completion of the job, he makes a similar check mark in the space that indicates the finishing time. The exact time is computed in the cost department. To illustrate: Suppose a job is started at 7 A. M. and is done in 6½ hours. The time will be checked at 7 A. M. and again, if an hour is allowed for lunch, at 2:30 P. M. This really shows 7½ hours elapsed time, but in the cost department, the lunch hour will be allowed for, and the computed time will be correct. Another form of job card, intended for use where jobs require more than one day, is shown in Fig. 14. With this card, it is intended that the starting and finishing time shall be entered in the ordinary way, and the name of the operation checked. [Illustration: Fig. 15.

Mechanical Time Recorders.= For the same reasons that they are best for making records of total time, for pay─roll purposes, mechanical time recorders are best for obtaining production time records. Whether the responsibility of making the record rests on the workman or a clerk, it is always better to have the actual recording done automatically whenever it is possible to do so.
