Employee performance reviews are not just management tools — they are potential evidence in future employment litigation. In California wrongful termination, discrimination, and retaliation cases, performance reviews are routinely scrutinized by opposing counsel and courts.
Best practices for conducting legally defensible performance reviews include:
- Use objective, measurable criteria.
Tie evaluations to defined job duties, written expectations, and documented performance metrics. Avoid vague phrases such as “not a good fit” or “poor attitude” without explanation. - Be honest and consistent.
Inflated or overly positive reviews followed shortly by termination significantly undermine an employer’s credibility. If performance is deficient, the review should reflect that. - Align reviews with prior documentation.
Performance reviews should not contradict prior disciplinary records or informal feedback. Inconsistency creates litigation risk. - Avoid discriminatory or biased language.
Comments referencing age, personality traits, medical issues, or protected characteristics can later be used to support discrimination claims. - Document improvement expectations clearly.
If performance is below standard, specify what improvement is required, within what timeframe, and what support is being offered.
In California employment disputes, poorly drafted performance reviews often become a central issue. Accurate, objective, and consistent documentation significantly strengthens an employer’s defense.
