Interviewer instructions
<span class="h2">7.5 Battery III. Work context</span>
<br />Starting with this battery of questions and up to six, the information you obtain will refer exclusively to the main job of the employed population, such that it could have been performed during the reference week or they could have been absent from it, but with return assured.</p>
<p>The purpose of this battery of questions is to identify the person's position or job, their title in the occupation, the size of the economic unit and how long they have been on the job, among others. In addition, based on title in the occupation, the purpose will be, in the case of:</p>
<div class="i1">- Independent workers, identify their level of autonomy and the line of their activity.<br />- Subordinate workers, identify whether they have a written contract and access to employment benefits, as well as the form in which they accessed their job.</div><span class="em">Question 3e</span>
<br />This question is asked to independent workers to identify whether they are owners of a single type of business or various with different lines of business.</p>
<p>[Omitted figure]</p>
<p>Conceptual clarifications:</p>
<div class="i1"><span class="ital">Type of business or activity (line of business). </span>This is the type of goods and services a company or business generates according to its form of operation or organization.<br /><span class="ital">Company or business. </span>The economic unit that, under a single owner or controlling entity, combines actions and resources to perform activities of the production of goods, purchase-sale of merchandise or provision of services, whether or not for commercial purposes.<br /><br />To perform its activities, an economic unit may have one or more establishments; or may work on the street, in an improvised stand, at the home of their customers or in their own home. In the case of economic units with more than one establishment, there may be branches or auxiliary units.<br /><br /><span class="ital">Establishment. </span>The economic unit distinguished by having an address, that is, a place where it can be permanently located, as it has fixed construction or facilities where actions and resources are combined for the production of goods, purchase-sale of merchandise or the provision of services.</div><p>An auxiliary unit is an establishment that has an independent physical location, where only activities are conducted in support of other establishment(s) with which it shares its business name. It does not, therefore, provide services to third parties, that is, it does not have the authority to provide services to the public, make sales, produce or manufacture products. The purpose of its services is to facilitate the main activity of the entire company to which it belongs; therefore, when obtaining the information, you must identify the main activity to which the entire company is dedicated, not that of the auxiliary establishment.</p>
<p>An auxiliary unit is an establishment that has an independent physical location, where activities are conducted only in support of another or other establishments with which it shares its business name. It does not, therefore, provide services to third parties, that is, it does not have the authority to provide services to the public, make sales, produce or manufacture products. The purpose of its services is to facilitate the main activity of the entire company to which it belongs; therefore, when obtaining the information, you must identify the main activity to which the entire company is dedicated, not that of the auxiliary establishment.</p>
<p>Examples of auxiliary units:</p>
<div class="i1">- Warehouse (located at an address independent from the factory) that stores the fabrics and batting (raw materials) and the blankets and quilts (finished product) from the factory that generates these types of products.<br />- Administrative offices, located at another address, of a mining company whose mission is to conduct, exclusively, administrative and financial control of this company.<br />- Mechanical workshop of a government agency in which only vehicles of that government entity are repaired and maintained.</div><p>In conclusion, the distinction between productive and auxiliary establishments is extremely important, considering that the purpose of the survey, and this question in particular, is to identify the main activity to which the productive units are engaged, if they perform more than one, not those performed by the auxiliary establishments. Battery of questions 4 examines this distinction in more detail.</p>
<p>It is important to say that not all economic units for which the employed population works have formal facilities like those listed above. There are others made of rustic materials: floor-anchored sheet metal stands, or stands that are installed in one place during the workday and taken down at the end of the day, as in the case of an assembled stand, motorized vehicles or not (for example, a hand cart on which prepared fruit is sold to the general public, and whose normal center of operations is the corner of a park).</p>
<p>Thus, a company or business in one or more establishments may be dedicated to:</p>
<div class="i1">- The production of goods and services of a single line of business: manufacturing footwear motor vehicles, manufacturing military uniforms, fighting crime, bee keeping, commerce, washing other people's clothes.<br />- The production of two or more lines of business in two or more establishments at the same time: fishing and manufacturing hats; raising bees and quarry extraction; selling food and doing printing work on clothing.</div><p>In situations like those described in the second bullet point, you must read the note of caution in option 2 to identify which is the main business:</p>
<p>[Omitted figure]</p>
<p>The informant should define the principal business, based on their own assessment. If they respond that they don't know which to choose as the principal, help them by telling them to consider, first, which has the support, regularly, of the larger number of workers.</p>
<p>When you reach this question you will be in a position to verify whether business activity defined as principal is consistent with the name of the occupation recorded in question 3; otherwise, ask additional questions to guaranty that the information obtained and which you must continue recording as principal until battery of questions 6, will refer precisely to the occupation you entered as principal.</p>
<p>Instructions:
<br />1. A single type of business or activity</p>
<div class="i1">- Independent workers who are dedicated to a single type of business or activity, regardless of whether it is performed in one or in different physical locations, as it is the same controlling economic unit (owner).</div><p>Examples:</p>
<div class="i1">- The office of market studies of consumer preferences which has more than one branch.<br />- The owner of a chain of carts that sell food on different sites in a city.<br />- Independent workers of economic units that involve vertical integration processes in the generation of its goods and services.</div><p>Vertical integration refers to a single company undertaking all productive processes necessary to generate its goods or services: production, transportation or distribution and sales. In said productive process, the product that results from one of the phases serves, in turn, as the supply of another process, until one or more products are obtained, as a result of the process as a whole.</p>
<p>Examples:</p>
<div class="i1">- The independent worker whose economic unit is dedicated to the cultivation of forage corn or alfalfa for raising beef cattle and milk production.<br />- Raising hogs for slaughter and the sale of meats.<br />- Collecting catkin and making wax.<br />- Independent workers who have a single establishment in which they undertake their own activities from a different economic sector, in which case you will have to identify the main activity to which the economic unit is engaged, since the information you compile in the next question and in battery of questions 4 should refer to this one.</div><p>Examples:</p>
<div class="i1">- A pharmacy owner who in the same establishment, in addition to selling medications, has a photo processing and printing service, as well as the preparation and sale of food for immediate consumption.<br />- The owner of a salon who in the same establishment, in addition to personal grooming services, sells various products.</div><p>2. Several types of businesses (with different locations)</p>
<div class="i1">- Independent workers who are engaged in more than one type of business or activity, as long as each of these lines of business are performed in different establishments.</div><p>To check this option, it is mandatory that the following two requirements are met: engaged in more than one line of business and each of the lines is conducted at a different location.</p>
<p>Examples:</p>
<div class="i1">- One businessperson has a carwash and an auto repair shop.<br />- A worker whose first business consists of preparing and distributing corn and potato chips in different stores in the town and the second, of growing broccoli and beans.<br />- An independent worker who gives private language classes and prepares banquets for special events.</div><p>The underlines in the preceding examples indicate that these activities were defined as the principal ones, in which case the sequence the interviewer should follow should focus on these when obtaining the information for the remaining questions through battery 6.</p>
<div class="i1">- Sequence to follow. Regardless of the option you circle, continue with question 3f.</div>
