Night Shift Vacancy and Overtime
A 24/7 core laboratory needs two technologists on site 16 hours per day, 365 days per year-11,680 productive hours. Each FTE provides 1,850 productive hours after vacation, holidays, sick leave, and education. The section is authorized 6.4 FTE but has 5.4 FTE filled after a resignation eight weeks ago. Overtime is running at 15% and 32 hours per week of agency staff are being used at $72/hour. Base pay is $34/hour; overtime is time-and-a-half; benefits are 28% of base salary. Night differential is $4.50/hour, while the local market is $6.00/hour. Two offers have been declined because of the shift. Tenured night staff resist changing from 8- to 10-hour shifts, and two specimen-labeling errors occurred in the past three weeks.
1. Calculate the FTE gap and compare the 12-week cost of overtime, agency staff, and hiring one full-time technologist.
Read the worked answer
Required FTE = 11,680 / 1,850 = 6.31. Filled = 5.4, so the gap = 0.91 FTE = about 1,684 productive hours/year = 32.4 hours/week.
12 weeks (about 384 hours):
- Overtime: 384 × ($34 × 1.5) = 384 × $51 = $19,584.
- Agency: 384 × $72 = $27,648.
- Hire 1.0 FTE: 480 paid hours × $34 = $16,320; with 28% benefits = $20,890; productive hours are lower during onboarding.
Overtime is the cheapest immediate bridge; agency is the most expensive. Hiring is sustainable but has a lead time. Recommendation: use overtime short-term, stop agency, and post the position with a market differential. The difference between overtime and agency over 12 weeks is about $8,000, which can fund recruitment and retention.
2. What nonfinancial factors should drive the decision, and what retention changes would you recommend?
Read the worked answer
Nonfinancial factors: fatigue and error risk (two labeling errors), single-coverage safety, morale, tenured staff resistance, continuity, and patient experience.
Retention changes: raise the night differential to the market $6.00; offer self-scheduling and 10-hour shifts only after a staff vote; provide predictable rotations; conduct stay interviews; and create a career ladder. A $1.50 differential costs about $3,552/year per FTE with benefits (1,850 × $1.50 × 1.28), far less than agency. Include staff in schedule redesign so the change is owned by the team rather than imposed.
3. The CFO directs you to eliminate the 0.5 FTE relief position to balance the budget. How do you respond?
Read the worked answer
Eliminating 0.5 FTE relief increases the gap to about 1.4 FTE and forces more overtime and agency use, which is more expensive and unsafe. Present a one-page comparison: relief cost versus overtime/agency premium and error risk. Offer alternatives: reduce send-outs, renegotiate service contracts, adjust non-stat testing hours, or use the hospital float pool.
If the CFO insists, document the staffing risk and ask for a written decision. Do not silently accept a plan that leaves one technologist alone on nights. The manager's job is to make the trade-off explicit, not to absorb an unfunded cut that threatens patient safety.
