What BLS wages measure. OEWS estimates describe straight-time gross wages, not just base salary and not total compensation. They include commissions and production bonuses. They exclude overtime, shift differentials, nonproduction bonuses and benefits. Discuss travel, per diem, tool and truck allowances separately. Percentiles describe the occupation's wage distribution, not seniority, plant size, job complexity or credentials. Licensing, union agreements and prevailing-wage obligations depend on the work and assignment; these figures do not establish a premium for them.
