ABI's exclusion of 81 employees from union dues under CBA contested; SC ruled them rank-and-file, eligible for union membership, no unfair labor practice.

Case Summary (G.R. No. 162025)

Dispute over Union Dues Deduction

ABI ceased deducting union dues for 81 employees it deemed excluded under the CBA. Affected employees included 18 QA sampling inspectors and machine gauge technicians (Quality Control Staff), 20 checkers in various departments, and approximately 43 secretaries/clerks reporting to division managers.

Grievance and Arbitration Submission

Job descriptions showed secretaries/clerks and checkers performed routine recording, monitoring, and clerical tasks without evidence of accessing confidential management or labor-relations information. Numeric proliferation of positions for single departments suggested mere reclassification rather than substantive confidential functions.

Quality Control Staff and Sampling Inspectors

Sampling inspectors and gauge technicians undisputedly belonged to Quality Control Staff and were excluded. However, checkers lacked proof of involvement in sensitive product formulas, trade secrets, or policy formulation, precluding their
