Many organizations try to solve staffing gaps by asking more of the people they already have: extra shifts, longer days, and mandatory overtime. Over time, this strategy erodes the workforce you are trying to protect. Studies across hospitals and long-term care consistently link extended shifts, heavy workloads, and inadequate staffing to higher burnout, job dissatisfaction, and intention to leave.

Research using large samples of hospital nurses has found that nurses working 10‑ to 12‑hour shifts are significantly more likely to experience burnout and dissatisfaction than those working shorter shifts. In one study, nurses working shifts of 10 hours or longer were up to 2.5 times more likely to report burnout and job dissatisfaction, and the longest shifts were associated with worse patient outcomes.

Burnout itself is strongly tied to turnover. National analyses have shown that a substantial share of nurses who leave positions cite burnout as a primary reason, and long work hours and inadequate staffing are repeatedly identified as core drivers.

Yet many scheduling models are still built around maximizing coverage rather than designing for human capacity. Schedules that routinely push nurses to the edge of their physical and emotional limits may appear efficient in the short term, but they create costly turnover and quality risks over time.

Kace Premier’s philosophy is to use PRN and contract staffing as tools to protect the core workforce, not as levers to squeeze more hours from them. That aligns with evidence indicating that adequate staffing and reduction of excessive hours reduce burnout, improve satisfaction, and support better care quality.

Practically, leaders can start by monitoring basic “pressure indicators” in scheduling: number of consecutive shifts worked, weekly hours per clinician, frequency of last‑minute schedule changes, and use of mandatory overtime. Studies show that inadequate staffing and lack of control over shift length are associated with higher burnout and exhaustion.

Organizations can then establish guardrails—such as caps on consecutive shifts, limits on weekly hours, and rules for using PRN staff before overloading core employees. Evidence suggests that reducing reliance on overtime and improving staffing adequacy are associated with better nurse outcomes, including reduced burnout and intent to leave. (Nurse Staffing, Work Hours, Mandatory Overtime, and Turnover in Acute Care Hospitals – International Journal of Public Health)
Schedule design also needs to incorporate recovery time and predictability. Nurses who have more control over their schedules and adequate rest report better well‑being and lower burnout risk. (Shift Work Characteristics and Burnout Among Nurses – NIH‑indexed study)
By treating scheduling as a strategic retention tool rather than a purely operational task, leaders can move from burnout‑driven churn to a more stable, sustainable workforce. Kace Premier Medical Talent supports clients in building staffing models that balance coverage demands with the realities of clinician capacity, using supplemental staffing to protect—not exhaust—the core team.
