Interviewer instructions
<span class="h2">7.9 Battery VII. Secondary job</span>
<br />The purpose of this battery of questions is to identify the population that has a second job, to be characterized based on the occupation or trade performed and the type of economic unit for which they work, the activities to which they are dedicated, the type of medical care they have, the size of the economic unit, the number of days and hours worked the week before the interview and the approximate amount of their income.</p>
<p><span class="em">Question 7</span>
<br />This question is asked to employed persons to find out if they performed or had a second job during the reference period, in order to characterize it throughout this battery of questions.</p>
<p>[Omitted figure]</p>
<p>Conceptual clarifications:</p>
<p>In general terms, in order to determine whether a person performed or had a second occupation during the reference period, take into consideration the same criteria considered in battery of questions 1 to define whether or not a person was employed, that is: if they went to a job the week before the interview or if during this period they were absent from their job, but received economic income or even if they returned to work the week the survey is conducted.</p>
<p>Like in the main job, it is the informant who defines what their secondary job is, if they have more than two, and you may only help them if they have questions defining it, taking as a reference the same criteria listed in question 3, to define the main job: to which the most time is dedicated, which earns the most income, which have they worked the longest, which has the best welfare benefits.</p>
<p>Instructions:</p>
<div class="i1">- Identification by the informant of the secondary job. If the person has two or more jobs apart from the main one, ask them to define one of them as secondary, based on their own assessment; if they respond they do not know how to define the secondary, help them, taking as a reference the same criteria considered in question 3 to identify the main job.<br />- Verification of the existence of a second job. In addition to the preceding criteria, it is appropriate for you to analyze the information from the main job, with which could be considered the secondary job, in order to determine whether the interviewee effectively has another job apart from the main one. These criteria are set forth below:<br />- Subordinate worker of two different economic units. In this case it is relatively simple to know if an employed person has a second job, if they work for different economic units; this information can be corroborated by comparing what is recorded in questions 4 and 4a, and in questions 7, 7a and 7b.</div><p>In the case of teachers, respect the spontaneous response if they say they have two jobs. Consider them to have a single job if they state they work on two or more school buildings, or on the same school building, but in different shifts with the idea of supplementing the work schedule, receiving a single salary.</p>
<p>If the information indicates that they perform two jobs: teacher and director or teacher and prefect (hall monitor), or any other combination, ask if they receive an income for each position; if the response is yes, consider them to have another job apart from the main one; otherwise, do not.</p>
<div class="i1">[Omitted table]<br /><br />- Independent worker. Consider a person to have two or more jobs only if they meet the following two conditions:<br />- If they perform a different job on both jobs; that is, in the main job and the secondary job (questions 3, 7 and 7a); and<br />- If their economic unit is dedicated to more than one line of business, performing each in different establishments (addressees). To corroborate this situation, consult the information from questions 3e, 3f, 4a, 4f, 7b and 7c.</div><p>Note that the concept of establishment is the same as the one in question 3f, such that if a worker is dedicated to two or more occupations and two or more activities, and they are even performed in two improvised, fixed or semi-fixed stands, located at different addresses, they are considered to meet the defined requirement, and even if one of the jobs has an establishment and the other does not.</p>

<p>Example 7
<br />[Omitted table]</p>
<p>Do not consider an independent worker to have two or more jobs if they do not meet the stated conditions.</p>
<p>In the case of independent workers who are engaged in various trades ("jack-of-all-trades"), like plumbing, gas fitting, painting facades, during the reference week in the home of their clients, do not consider them to have a second occupation, they have, in any case, different clients.</p>
<div class="i1">- Consistency of the information. If, when analyzing the information, you find out, based on the cited criteria, that the person does not have two jobs, return to the respective questions and correct the information, then continue filling out question 8.<br />- Criteria to classify the second job in question 7. Once the presence of a second occupation has been identified, classify it in this question according to the type of job, trade or position the person normally performs, even if the tasks described in question 7a do not match the trade, position or job.<br /><br />Examples:</div><div class="i2">- Fermín is a cattle farmer (independent worker), although during the reference week he only worked on repairing the corral and the ranch in general. Circle option 3 working his land or parcel and/or raising animals.</div><div class="i2">- Basilio is a merchant, but during the reference week worked distributing flyers to promote his business and seeking new products for it. Circle option 1 Selling or making products for sale (foods, beauty products, clothing).</div><p>Before stating the criteria to follow to classify the information in each response option, it is worth noting that the detail of the options includes the position within the occupation, such that the first four are aimed at independent workers and the rest to subordinate workers; however, it is worth further explaining that the fourth option is common for both independent and subordinate workers.</p>
<p>The specific instructions to classify the information are listed below, option by option.</p>
<div class="i1">1. Selling or making products for sale (foods, beauty products, clothing)</div><div class="i2">- Independent workers who are dedicated to commerce, works construction, industrial or artisanal manufacturing.<br />- Independent workers who perform activities related to the extraction and exploitation of metallic and non-metallic minerals.</div><div class="i1">2. Providing services (giving classes, cutting hair, washing other people's clothing)</div><div class="i2">- Independent workers who perform any type of service, established or not, such as those who provide transportation related services; management and distribution of cultural information and products; real estate and furniture rental services; professional, scientific and technical services; personal services, repair and maintenance activities, etc.</div><div class="i1">3. Working their land or plot and/or raising animals</div><div class="i2">- Independent workers who perform primary sector activities (agriculture, livestock, forestry, fishing and hunting), including self-consumption activities in this sector, with the exception of collecting wood.</div><div class="i1">4. Working for tips, commission or by the piece, service or job completed</div><div class="i2">- Subordinate workers who work for tips, commission, percentage or by the task, regardless of the economic sector under which their occupation falls.</div><div class="i1">5. Working as a salaried employee (wage, salary or daily wage)</div><div class="i2">- Subordinate workers who work for a fixed wage, salary, daily wage, regardless of the economic sector to which they pertain.</div><div class="i1">6. Assisting in some business or on lands of a relative or other person</div><div class="i2">- Subordinate workers who perform support activities in the economic unit of a relative or other person without receiving any pay for doing so.</div><div class="i1">7. Have no other job</div><div class="i2">- People who have only one job.<br />- Sequence to follow. If you circled options 1 to 6, continue with question 7a; if you circled options 7 or 9, go to question 8.</div>
