Although employers are required to provide drinking water on the job, many workers don't drink enough of it. Some may feel their supervisor doesn't approve or they don't want to take time out when working at a piece rate. Others tend to wait until they feel thirsty. Whatever the reason, workers put themselves in danger by not drinking enough water or not drinking water often enough.

All heat illnesses can cause harm, and one of them -- heat stroke -- can kill. It is useful for people who work hard outdoors to understand how the body generates and copes with heat. Most important is the connection between fluid loss and heat illness.

Some of the heat that people have to deal with comes from the sun and surrounding air, but most of the heat that stresses workers is created by their own bodies. The body generates heat when moving muscles and limbs. It even produces some heat at rest.

To cool itself, the body first increases blood flow toward the body surface. From the skin, heat can be released. However, hot or humid weather slows the release.  To compensate, sweat glands to kick in.  Sweat carries heat out faster through pores.

Sweating draws water from the blood stream, leaving less fluid to carry oxygen and nutrients to the muscles, brain and other internal organs. The thicker blood makes the heart work harder. If the lost fluid is not replaced by drinking, this process can cause heat illness. The first stage of head illness is heat rash. The problems can get much worse – including cramping, confusion and, eventually, collapse.

If you notice heat illness symptoms in yourself, stop working, sit in the shade, drink water, loosen clothing, and tell your supervisor as soon as possible.  If you notice symptoms in co-workers or friends, you can help them take these potentially life-saving steps. 

The most common and costly agricultural injuries are back injuries. Many back injuries are related to lifting and carrying heavy loads. Awkward postures and slips and falls are also common causes of back injuries.

Research has shown that the use of back belts and stretching exercises don't help prevent back injuries. The best way to avoid back injuries is by carrying loads of no more than 50 pounds. In research studies, when loads of harvested grapes being carried by farmworkers were kept to less than 50 pounds, back injuries occurred four times less often. UC researchers now recommend that smaller containers be used in the field for carrying picked fruit – including smaller picking bags in orchards.  Where smaller containers are not available, try not to fill larger containers to their fullest.  While this may require more walking to empty containers, research in grape harvest showed that workers who carried lighter loads had more energy to work faster later in the day and so did not lose productivity or income. 

When confronted with a load of more than 50 pounds seek help from a co-worker and make sure the lift is coordinated so one of you doesn't wind up holding the entire load.

Don't take chances with your back by routinely lifting loads over 50 pounds.  When you hurt your back, you risk not only your employment and being able to provide for your family, but also your enjoyment of life with friends and family. Working smarter reduces injury risk and doesn't have to cost you income.

The stress of workplace conflicts can put farmworkers at a greater risk for on-the-job injuries. Frustration and anger can distract workers from their focus on the task at hand and on completing that task safely and properly. When disagreements between workers or with supervisors are poorly dealt with, the outcome can be a sense of psychological distance, such as lasting feelings of dislike, alienation and disregard.

The first thing that gets in the way of resolving conflicts is the natural desire to explain our own side first, sometimes in a loud or harsh manner that creates more animosity. The second obstacle is being an ineffective listener.

Listening is more than being quiet, it is actively seeking to comprehend the other person's point of view. Fear can also prevent conflict resolution  –  the fear of losing something or the fear of looking foolish. Finally, the assumption that one of the contending parties has to lose if the other is going to win can block a resolution.

Researchers have found simple and effective tools to reach positive solutions to disagreements. First, encourage others to explain their side first. Then they will be more likely to listen to your side. When your opponent is speaking, resist the tendency to interrupt with objections, no matter how unfounded some of the comments may seem. And don't spend the time composing a perfect comeback. Really listen.

When it's your turn to talk, try not to focus on your solution, but making sure that the needs of the other person as well as yours are considered. You may be surprised to find that you have more in common with your adversary than you thought.

Many farm jobs require repetitive motion – doing the same task over and over again. Though sometimes unavoidable, this type of work can cause serious, chronic injuries. Everyone knows of someone who developed a “bad back” after years of field work. 

There are only a few ways of preventing such long-term injuries in jobs requiring high rates of repetitive motions such as cutting, picking, bending, lifting and carrying.  Where practical, many work crews rotate jobs so that no one has to do such a job for more than an hour or two at a time.  Job rotation is a good way to reduce the continued stress of such jobs. 

Some jobs have built in breaks – such as the need to move from the picking area to another location where the product is loaded into bins. If the job does not have built in breaks, repetitive motion injuries can be avoided with “micro breaks” of a few seconds every 15 minutes to stop doing the work.

Another type of work break that UC researchers have shown to be effective in reducing pain and other symptoms of highly repetitive tasks is to add a five-minute work break to every working hour that does not already have a break. In other words, take just five minutes to stop working each hour in which you don't have a morning, lunch or afternoon break.
