What is inside the BLS pay figure
For an operations offer, separate standby availability payments from wages for hours actually worked. BLS excludes on-call waiting pay and shift differentials. Ordinary straight-time wages for work performed are not excluded by the on-call rule.
| Component | In the BLS figure? | Note |
|---|---|---|
| Base rate and guaranteed pay | Included | BLS counts the "base rate" and "guaranteed pay". |
| Production and incentive pay | Included | BLS counts "incentive pay including commissions and production bonuses". |
| On-call waiting or availability pay matters here | Left out | BLS excludes payment for time spent awaiting a call to work, not ordinary wages for hours actually worked. BLS on-call pay definition. |
| Overtime pay | Left out | BLS excludes "overtime pay". Straight-time pay only. |
| Shift differentials matters here | Left out | BLS excludes "shift differentials", so night and weekend premiums are not in the figure. |
| Project-completion and discretionary bonuses | Depends on the terms | Guaranteed pay and production incentives are included. Discretionary nonproduction bonuses are excluded. Check how the payment is defined. |
| Per diem, travel and relocation | Left out | BLS does not name these as wages. They are expense reimbursements and are not in the figure. |
| Benefits and employer costs | Left out | BLS excludes "employer costs for supplementary benefits". |

What the published rows say about Critical Facilities Technician Level II pay in the United States
Critical Facilities Technician Level II maps to Stationary Engineers and Boiler Operators, SOC 51-8021. For the United States, the May 2025 OEWS annual median is $78,620; the middle half runs from $63,160 to $101,150. This is a broader occupation, not a separate wage estimate for this exact job. BLS does not separate seniority titles that share this row. Set out the shift, switching authority and on-call duties before comparing offers. A site-based position and a traveling service job can share a wage row without offering the same working conditions.
The middle-half spread is $37,990: $15,460 from the 25th percentile to the median and $22,530 from the median to the 75th. The upper interval is wider. Use these points to compare an offer, not to price a junior or senior hire. Percentiles are not experience bands, and this distribution alone does not explain why individual workers earn different amounts.
