Enterprise Survey [en/oth]
The Occupational Wages Survey (OWS) 2002 is the third in the series since the survey was re-designed to focus on the wage rates of relatively skilled occupations in industries likely to be affected by the changing global and economic structure. The survey aims to generate statistics for wage and salary administration and for wage determination in collective bargaining negotiations.
The 1989-1995 OWS was conducted every semester except for the 1990 OWS, which was conducted quarterly. For occupational wage data, the reference periods were the end of each calendar quarter while for the distribution of time-rate workers, the reference periods were the end of June and December. Except for the 1994, 1995 and 1997 survey rounds whose data collection was undertaken by the National Statistics Office, the BLES handled the field operations.
For the 1997 and 1999 rounds, October was adopted as the reference period of the survey for international comparability since the Bureau of Statistics of the International Labour Office has an annual inquiry on occupational wage rates and normal hours of work where October is the reference period of the data.
Although the 1997 and 1999 survey rounds of the revised OWS had October as reference, data collection did not commence immediately after the reference point as the fiscal year of the Philippine government ends in December and data collection can only commence in the next year (March/April). Experience from past surveys of the BLES showed that data retrieval from establishments during the last months of the year is quite low or slows down for surveys whose data collection starts late in the year.
Another consideration in the shift of the reference period of the third round of the OWS from October 2001 to June 2002 was the need to capture the effects of minimum wage adjustments. A survey conducted by the BLES revealed that a substantial proportion of establishments based their wage adjustments on government fixed wages. In some instances, minimum wages were being implemented on a staggered basis. In the National Capital Region (Metro Manila) where at least half of time-rate workers are found (based on the 1999 OWS), a Wage Order mandated a staggered adjustment with effectivity dates in November 2001 and February 2002. The shift in the reference period improved the timeliness of the data from 17 to 12 months after reference period.

Sampling
Statistical unit: The statistical unit is the establishment. Each unit is classified to an industry that reflects its main economic activity---the activity that contributes the biggest or major portion of the gross income or revenues of the establishment.
Survey universe/Sampling frame: The sampling frame used for the survey was taken from the List of Establishments of the National Statistics Office. On a partial basis, this is regularly updated based on the responses to other surveys of the BLES, establishment reports on retrenchments and closures submitted to the Regional Offices of the Department of Labor and Employment and other establishment lists.
Sampling design: The OWS is a complete enumeration survey of non-agricultural establishments employing 50 persons or more in the National Capital Region.
Sample size: For OWS 2002, number of establishments covered was 5,954 of which, 3,974 were eligible units.
Note: Refer to Field Operations Manual
Not all of the fielded questionnaires are accomplished. During data collection, there are reports of permanent closures, non-location, duplicate listing and shifts in industry and employment outside the survey coverage. Establishments that fall in these categories are not eligible elements (three consecutive survey rounds for "can not be located" establishments) of the frame and their count is not considered in the estimation. Non-respondents are made up of refusals, strikes or temporary closures, can not be located (less than three consecutive survey rounds) and those establishments whose questionnaires contain inconsistent item responses and have not replied to the verification queries by the time output table generation commences.
Respondents are post-stratified as to geographic, industry and employment size classifications. Non-respondents are retained in their classifications. Sample values of basic pay and allowances for the monitored occupations whose basis of payment is an hour or a day are converted into a standard monthly equivalent, assuming 313 working days and 8 hours per day. Daily rate x 26.08333; Hourly rate x 208.66667.
The response rate in terms of eligible units was 78.7%.
Estimates are obtained by simple expansion, i.e. by multiplying the sample values at the cell level (industry and employment size) by the corresponding blowing-up factor which is the ratio of the estimated population of establishments to the number of responding establishments. These estimates are then aggregated to the desired totals.
Dividing the estimated total basic pay (or total allowances) in each occupation by the corresponding estimate of time rate workers on full-time basis results to the average monthly basic pay or average monthly allowances as the case may be. The monthly average basic pay and monthly average allowances are then summed up to provide the average monthly wage rates by occupation.
The median monthly basic pay is computed from the estimated distribution of workers by monthly basic pay. On the other hand, the median monthly allowance is computed only for those workers reported with allowances.
Survey instrument
The 2002 OWS questionnaire is made up of the following sections:

This contains the address box for the establishment and other particulars.
Survey Information (Page 2)
This section provides information on the purpose of the survey, coverage, reference period, collection authority, authorized field personnel, confidentiality clause, due date, availability of results and assistance available.
Part A: General Information (Page 3)
This part inquires on the main economic activity, major product/s, goods or services, total employment, ownership (with foreign equity or wholly Filipino), spread of operations (whether establishment is a multinational), market orientation (for manufacturing only, engaged in export or domestic market only), presence of a union and existence of a collective bargaining agreement in the establishment.
Part B: Employment and Wage Rates of Time-Rate Workers on Full Time Basis (Pages 4 - 5)

Part C: Employment and Wage Rates of Time-Rate Workers on Full-Time Basis in Selected Occupations (Pages 6 - 11)
For each occupation covered, the establishment is asked to report the time unit of work (hourly, daily, monthly), corresponding basic pay per worker and number of workers. Similar data are also asked for workers in the occupation that are given regular allowances. The total number of workers disaggregated by sex in each monitored occupation is likewise requested
Part D: Key and Representative Occupations in the Establishment (Page 12)
This asks for the occupations and corresponding employment of those considered as unique to the industry/sector to which the establishment belongs, employs the most number of works, historically important in the wage structure or emerging/has a high growth potential.

Designated Survey Supervisors were assigned to supervise the field operations in their areas of assignments. They also performed the following duties:
- Check completeness and consitency of entries in retrieved questionnaire and retun for verification those needing further clarifications to concerned enumerators;
- Conduct follow-ups, spot checks and verification;
- Monitor and evaluate the performance of field personnel for purposes of payment of salaries; and
- Ensure the confidentiality of the data provided by the respondents.
On a project basis, employees are hired to personally deliver and retrieve the questionnaires from the establishments. In some instances, questionnaires are mailed to establishments in less accessible or conflict prone areas, in which case a selfaddressed envelope is provided. The establishments may also submit the accomplished questionnaires through fax. Delivery of questionnaires starts in August of the reference year and retrieval will commence after all questionnaires have been delivered or within 10 working days from delivery to an establishment or on a date agreed upon by the contact person and the enumerator. The basic data originate from the payroll records of establishments.
To assist the respondents in classifying their job titles that may have different nomenclatures than the 1992 PSOC, an occupational sheet is inserted in the questionnaire of an establishment whose industry belongs to the 43 predetermined industries that will be monitored on occupational wage rates. This sheet contains a list of the occupations being monitored in each of the industry and their corresponding job descriptions in accordance with the 1992 PSOC.
The occupations may vary across establishments depending on their industry classification. Establishments that fall outside the 43 industries are not given occupational sheets. However, in the event that the industry of such establishment has been misclassified in the sampling frame and it should have been provided an occupational sheet, the field staff is instructed to give the respondent the relevant occupational sheet. The two (2) occupations considered as benchmark (accounting and bookkeeping clerks; and unskilled laborers except janitors, messengers and freight handlers) and their corresponding job descriptions appear in the pertinent portion of the survey questionnaire. Wage rates of these occupations will be monitored in all 61 industries covered by the survey.
Data processing
Data are manually and electronically processed. Upon collection of accomplished questionnaires, enumerators perform field editing before leaving the establishments to ensure completeness, consistency and reasonableness of entries in accordance with the field operations manual. The forms are again checked for data consistency and completeness by their field supervisors.
The BLES personnel undertake 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 are returned to the establishments for verification, personally or through mail.
Note: Refer to Field Operations Manual Chapter 1 Section 1.10.
Data appraisal
The survey results are checked for consistency with the results of previous OWS data and the minimum wage rates corresponding to the reference period of the survey.
