Social and human service assistants have many job titles, including case work aide, clinical social work aide, family service assistant, social work assistant, addictions counselor assistant, and human service worker. They serve diverse populations with a range of problems. Their work varies, depending on the clients they serve.

With children and families, social and human service assistants ensure that children live in safe homes. They help parents get the resources, such as food stamps or childcare, they need to care for their children.

With the elderly, workers help clients stay in their own homes and under their own care whenever possible. They coordinate meal deliveries or find personal care aides to help older people with day-to-day needs, such as doing errands or bathing. In some cases, human service workers help look for residential care facilities, such as nursing homes.

For people with disabilities, social and human service assistants help find rehabilitation services that aid their clients. They may work with employers to adapt positions to make them accessible to people with disabilities. Some workers find personal care services to help clients with daily living activities, such as bathing or making meals.

With homeless people, assistants help clients meet their basic needs. They find temporary or permanent housing. They find places, such as soup kitchens, that provide meals. Human service assistants also help homeless people find facilities for other problems they may have, such as joblessness.

Construction laborers and helpers do many basic tasks that require physical labor on construction sites.

Construction laborers and helpers typically do the following:

• Clean and prepare construction sites by removing debris and possible hazards
• Load or unload building materials to be used in construction
• Build or take apart bracing, barricades, forms (molds that determine the shape of concrete), scaffolding, and temporary structures
• Dig trenches, backfill holes, or compact earth to prepare for construction
• Operate or tend equipment and machines used in construction, such as concrete mixers
• Help other craftworkers with their duties
• Follow construction plans and instructions from the people they are working for

Construction laborers and helpers work on almost all construction sites, doing a wide range of tasks from the very easy to the extremely difficult and hazardous. Although many of the tasks they do require some training and experience, most jobs usually require little skill and can be learned quickly. 

The following are occupational specialties:

Construction laborers do a variety of construction-related activities during all phases of construction. Although most laborers are generalists--such as those who install barricades, cones, and markers to control traffic patterns--many others specialize. For example, those who operate the machines and equipment that lay concrete or asphalt on roads are more likely to specialize in those areas.

Most construction laborers work in the following areas:

• Building homes and businesses
• Tearing down buildings
• Removing hazardous materials
• Building highways and roads
• Digging tunnels and mine shafts

Construction laborers use a variety of tools and equipment. Some tools are simple, such as brooms and shovels; other equipment is more sophisticated, such as pavement breakers, jackhammers, earth tampers, and surveying equipment.

With special training, laborers may help transport and use explosives or run hydraulic boring machines to dig out tunnels. They may learn to use laser beam equipment to place pipes and use computers to control robotic pipe cutters. They may become certified to remove asbestos, lead, or chemicals.

Helpers assist construction craftworkers, such as electricians and carpenters, with a variety of basic tasks. They may carry tools and materials or help set up equipment. For example, many helpers work with cement masons to move and set forms. Many other helpers assist with taking apart equipment, cleaning up sites, and disposing of waste, as well as helping with any other needs of craftworkers.

Many construction trades have helpers who assist craftworkers. The following are examples of trades that have associated helpers:

• Brickmasons, blockmasons, stonemasons, and tile and marble setters
• Carpenters
• Electricians
• Painters, paperhangers, plasterers, and stucco masons
• Pipelayers, plumbers, pipefitters, and steamfitters
• Roofers

Home appliance repairers install and repair household appliances, such as refrigerators, microwaves, and washer and dryers.

Home appliance repairers typically do the following:

• Travel to customers' homes
• Install home appliances
• Connect major appliances to water, gas, or electrical lines
• Inspect equipment that is not working
• Estimate repair or replacement costs
• Repair or replace broken parts
• Instruct customers on how to use appliances
• Bill and collect payment from customers

Home appliance repairers, often called home appliance repair technicians, usually travel to customers' homes to do their work. They use many basic handtools, including screwdrivers, wrenches, and pliers, to determine the cause of unusual noises, leaks, or excessive vibration. Some use more specialized tools, such as ammeters, voltmeters, and wattmeters, to check for electrical problems. After identifying problems, workers repair or replace defective belts, motors, heating elements, switches, gears, or other items. They also may tighten, align, clean, and lubricate parts as necessary.

Most technicians explain to clients how to use a new appliance. If necessary, they may show clients how to use different functions of a newly repaired appliance.

Technicians also keep records of bills, payments, parts used, and hours worked. If an appliance is under warranty, a technician may need to contact the appliance's manufacturer to be paid for the work they did.

When working on refrigerators and window air conditioners, repairers are required by law to conserve, recover, and recycle chlorofluorocarbon (CFC) and hydrofluorocarbon (HCFC) refrigerants used in cooling systems. Federal regulations also require that home appliance repair technicians document the capture and disposal of refrigerants. For more information, see the profile on heating, air conditioning, and refrigeration mechanics and installers.

Plumbers, pipefitters, and steamfitters install and repair pipes that carry water, steam, air, or other liquids or gases to and in businesses, homes, and factories.

Plumbers, pipefitters, and steamfitters typically do the following:

• Install pipes and fixtures
• Study blueprints and follow state and local building codes
• Determine the amount of material and type of equipment needed
• Inspect and test installed pipe systems and pipelines
• Troubleshoot and repair systems that are not working
• Replace worn parts

Although plumbers, pipefitters, and steamfitters are three distinct specialties, their duties are often similar. For example, they all install pipes and fittings that carry water, steam, air, or other liquids or gases. They connect pipes, determine the necessary materials for a job, and perform pressure tests to ensure a pipe system is airtight and watertight.

Plumbers, pipefitters, and steamfitters install, maintain, and repair many different types of pipe systems. Some of these systems carry water, dispose of waste, supply gas to ovens, or heat and cool buildings. Other systems, such as those in power plants, carry the steam that powers huge turbines. Pipes also are used in manufacturing plants to move acids, gases, and waste byproducts through the production process.

Master plumbers on construction jobs may be involved with developing blueprints that show where all the pipes and fixtures will go. Their input helps ensure that a structure's plumbing meets building codes, stays within budget, and works well with the location of other features, such as electric wires.

Plumbers and fitters may use many different materials and construction techniques, depending on the type of project. Residential water systems, for example, use copper, steel, and plastic pipe that one or two plumbers can install. Power-plant water systems, by contrast, are made of large steel pipes that usually take a crew of pipefitters to install. Some workers install stainless steel pipes on dairy farms and in factories, mainly to prevent contamination.

Plumbers and fitters sometimes cut holes in walls, ceilings, and floors. With some pipe systems, workers may hang steel supports from ceiling joists to hold the pipe in place. Because pipes are seldom manufactured to the exact size or length, plumbers and fitters measure and then cut and bend lengths of pipe as needed. Their tools include saws, pipe cutters, and pipe-bending machines.

They then connect the pipes, using methods that vary by type of pipe. For example, copper pipe is joined with solder, but steel pipe is often screwed together.

In addition to installation and repair work, journey- and master-level plumbers, pipefitters, and steamfitters often direct apprentices and helpers.

Following are examples of occupational specialties:

Plumbers install and repair water, drainage, and gas pipes in homes, businesses, and factories. They install and repair large water lines, such as those that supply water to buildings, and smaller ones, including ones that supply water to refrigerators. Plumbers also install plumbing fixtures--bathtubs, showers, sinks, and toilets--and appliances such as dishwashers, garbage disposals, and water heaters. They also fix plumbing problems. For example, when a pipe is clogged or leaking, plumbers remove the clog or replace the pipe. Some plumbers maintain septic systems, the large, underground holding tanks that collect waste from houses not connected to a city or county's sewer system.

Pipefitters install and maintain pipes that carry chemicals, acids, and gases. These pipes are mostly in manufacturing, commercial, and industrial settings. They often install and repair pipe systems in power plants, as well as heating and cooling systems in large office buildings. Some pipefitters specialize:

• Gasfitters install pipes that provide clean oxygen to patients in hospitals.
• Sprinklerfitters install and repair fire sprinkler systems in businesses, factories, and residential buildings.
• Steamfitters installpipe systems that move steam under high pressure. Most steamfitters work at campus and natural gas power plants where heat and electricity is generated, but others work in factories that use high-temperature steam pipes.

Parts Salespersons sell spare and replacement parts and equipment in repair shop or parts store.
