No ethical approval was required.  \nConsent to participate  \nNot applicable. This study did not involve human participants.  \nAI Use Disclosure  \nThe BiasLab evaluation system was developed with AI-assisted programming support. Large language model tools were used in the writing and debugging of code used to conduct the  \nautomated multilingual bias evaluation, data collection, and visualization described in this study. All code was reviewed and validated by the authors. No AI tools were used in the interpretation of results or the writing of this manuscript.  \nInformed consent  \nNot applicable.

The repository additionally includes the raw Excel output files for all six evaluated topics and the original analysis charts generated during the study.  \nAbstract  \nBackground: Large language models (LLMs) harbor systematic biases that are particularly consequential in workplace and HR contexts, where their outputs increasingly influence hiring, job design, and organizational decisions. Yet existing bias-evaluation approaches remain methodologically fragmented, limiting practitioners' ability to assess deployment risks.  \nObjective: This study introduces BiasLab, a multilingual dual-framing framework to quantify and compare directional output-level bias in LLMs, demonstrated across six workplace and HRrelevant topics.  \nMethods: BiasLab combines mirrored affirmative and reverse prompt pairs, randomized wrapper perturbations, fixed-choice response constraints, and polarity-aligned scoring.
