The patterns of work such as work hours and pauses, night work and shift rotation... 

There are two concerns about the effects of shift rotation and night work disruption of "circadian rhythms" and sociological costs, that is, effects on the worker s family life. 

Labor costs. In arriving at the total labor costs, there must be included social security costs, pension costs and any provisions for holiday pay. It may be desirable, where users take steam overnight, to apportion costs in such a way as to reflect the higher cost of labor employed on night work. 

Problem Sets Don t save them for Sunday night. Work out the problem sets so that YOU understand them. Get people s help when needed, but the most important thing is actually understanding how to get the right answer.

Homicide is another serious concern in some job settings. In 1995, homicide accounted for 16 percent of job-related fatalities. Workers most at risk are those who work late at night, work alone, and handle money. Taxicab drivers are the most susceptible and have a relative risk about 10 times higher than the typical worker. Other occupations that have a high relative risk of homicide include police and guards. 

Melatonin (= Ar-Acetyl-5-methoxytryptamine Regulin) (indole) circadian rhythm control - Chernobyl, Three Mile Island Bhopal all night work-related disasters... 

I spend days and nights, working with unusual intensity, trying to find out according to the indications of the Alchemists whether there is perhaps some remedy that would safely and effectively undermine the tenacity of this terrible disease, which affixed itself to the innermost recesses of the nerves. 

Potential Drawback - premium pay for night work, drop in productivity, and additional fixed costs for preparing the site for night work.
