Abstract

The Labor Turnover Survey (LTS) aims to generate quarterly data on labor turnover as indicators of labor market activity in large business enterprises. The main topics include total accession due to expansion and replacement, as well as employer-initiated and employee-initiated total separation.

The information gathered in this survey is intended to generate timely labor market signals as sound basis in planning, policy formulation and decision making in goverment, business and industry.

The top 25,000 corporations in the Philippines as listed by the Securities and Exchange Commission (SEC).

The universe was limited to the SEC list for two reasons: budget constraints and the decision to come up with manageable sample size that can provide DOLE officials with a quick and timely assessment of the labor market situations on a quarterly basis.

Sampling procedure

The enterprise is the unit of enumeration in the LTS and it has for its sampling domain 18 major industry groups (1-digit) based on the 2009 PSIC. The coverage of the survey was limited to business enterprises in Metro Manila due to budget constraints and in line with the instruction of DOLE officials to conduct a quick/timely assessment of the labor market activity through a sample survey with manageable sample size. Metro Manila accounts for one-third of the country's gross domestic product and about two-thirds of the total large business enterprises in the Philippines.

The sampling frame was extracted from the top 25,000 corporations in the Philippines as compiled by the Securities and Exchange Commission (SEC). The frame contains the names of 15,600 enterprises in Metro Manila listed in order of their gross revenue and sales in 2012.

For LTS 2013, the population size was 15,660. Since the proportion of the initial sample size to the population size is not negligible, a revised estimate of the sample size is obtained to take into account the finite population correction. To ensure the precision of estimates in each domain, the sample size (763) was allocated in each domain using Kish's allocation formula. The sample enterprises in each domain were drawn through simple random sampling.

Sampling deviation

A replacement of a sample enterprise was done when the sampled enterprise fell in one of the following situations during the field operation: cannot be located; refuse to answer; temporarily closed; duplicate of another sample enterprise; permanently closed; or on strike.

Mode of data collection

Cleaning operations

The data was manually and electronically processed. Upon collection of accomplished questionnaires, enumerators perform field editing before leaving the enterprise to ensure completeness, consistency and reasonableness of entries in accordance with the Field Operations Manual. The forms were again checked for data consistency and completeness by field supervisors. The designated personnel undertook the final review, coding of information on classifications used, data entry and validation and scrutiny of aggregated results for coherence. Questionnaires with incomplete or inconsistent entries were returned to the establishments for verification, personally or through phone interview.

Sampling error estimates

Not computed.

Data appraisal

The results were validated with the previous year results in particular, the trend and patterns of data distribution across industry.

Results were also checked in terms of their coherence with the results of the National Acounts, i.e, gross domestic product (GDP). It has been observed that the pattern of movement in the LTS data series closely follow that of GDP. This could be because NCR accounted for a sizeable share of GDP. The "rule of thumb" in LTS validation is that a high GDP is associated with a positive turnover rate and vice versa.

The Labor Turnover Survey (LTS) aims to generate quarterly data on labor turnover (accession and separation rates) as indicators of labor market activity in large business enterprises.

The sampling frame for the 2016 LTS is an integrated list from enterprises culled from the 2015 List of Establishments in the NCR prepared by the Philippine Statistics Authority (PSA) and the updated sampling frames of LTS 2014 and LTS 2015. This comprises 16,194 business firms/enterprises with an employment size of at least 20.

Sampling procedure

The enterprise is the unit of enumeration in the LTS and it has for its sampling domain the eighteen (18) major industry groups (1-digit) based on the 2009 PSIC. The survey covered business enterprises located in the National Capital Region (NCR) to provide a quick and timely assessment of the labor market activity through a sample survey with manageable sample size given the limited budget. NCR accounts for one-third of the country's gross domestic product and about two-thirds of the total large business enterprises in the Philippines.

The sampling frame for the 2016 LTS is an integrated list from enterprises culled from the 2015 List of Establishment in the NCR prepared by the Philippine Statistics Authority (PSA) in coordination with Service and Industry Census Division (SICD) the updated sampling frames of LTS 2014 and LTS 2015. This comprises 16,194 business firms/enterprises with an employment size of at least 20. This list was obtained and updated prior to the conduct of LTS for the first quarter of 2016. The updated frame was used in the sample size determination and sample selection for the first quarter survey round. The same sample size was retained in all quarters of the year.

After each survey round, all enterprises that responded are automatically considered as samples for the next survey rounds. To fill up the lack in the computed sample size, samples will be drawn by industry from the updated sampling frame. In cases where there are no enterprises to sample in some industries, the total number of samples needed for these industries will be allocated proportionally to other industries with available samples.

The sample enterprises in each domain were drawn through simple random sampling.

Sampling deviation

Replacement of sample enterprise is done when the sampled enterprise falls in one of the following situation during the field operation: (1) cannot be located; (2) refuse to answer; (3) temporarily closed; (4) duplicate of another sample enterprise; (5) permanently closed; or (6) on strike.
