Terms that cost money
Some HR vocabulary is administrative. These are the ones where a loose understanding tends to become expensive.
Exempt does not mean salaried. It means the role meets both a salary threshold and a duties test, and paying a salary alone does not achieve it. Regular rate is the figure overtime is calculated on, and it includes more than base pay — non-discretionary bonuses and shift differentials generally belong in it. Constructive discharge is when conditions are made bad enough that resigning is treated as a dismissal, which is why a resignation is not always the end of a matter.
Protected activity covers raising a complaint, cooperating with an investigation, or requesting an accommodation — and acting adversely towards someone afterwards creates a separate claim regardless of the original merits. Reasonable accommodation is an adjustment enabling someone to do their job, and the obligation is to engage in a genuine interactive process rather than simply to say yes or no.
