Great question! In addition to the direct costs of part-time wages and benefits, it's important to consider and compare the costs of chronic vacancies, high turnover, and missed opportunities. As you continue to weigh the costs and benefits (and costs of benefits) for more flexible staffing plans, make sure you are zoomed out far enough to see and analyze the whole picture.
For every day that a position goes unfilled, consider the actual and opportunity cost of district HR staff.
When district staff spend time on recruitment and hiring for positions that could be filled by a ready and waiting pool of part-time applicants, there is both the real cost of time on task as well as the opportunity cost of time and energy that could be redirected to recruitment and hiring for the most essential full-time positions. Then again, having more part-time staff may lead to some additional costs around timecard approval and simply having more employees. These costs must be considered and balanced.
Will these candidates necessarily always be part-time employees, or do some of them have the opportunity to grow into full-time certified staff with some support in the way of certification pathways? Is the district missing out on an opportunity to develop an internal pipeline of permanent full-time staff because of a reluctance to pay the benefits’ cost in the short-term?
How do the costs of part-time staff compare to the costs of finding, placing, and compensating long-term substitutes while incurring the ongoing HR costs to fill these positions permanently? In addition to the financial costs, what are the potential costs to student learning and/or school culture with a rotating cast of subs in lieu of consistent part-time employees? Might these financial costs be overshadowed by the hard-to-quantify costs of missed learning opportunities, student behavior challenges, and the social-emotional support of permanent staff—not to mention the ripple effects on the mental and physical health of other permanent staff?
Related to the direct and indirect costs laid out above for initial hiring, how might offering competitive benefits reduce turnover of part-time staff? Especially when you factor in the costs to school culture and climate that comes with staff turnover, it’s likely that the replacement costs of under-compensating staff will outweigh the marginal cost of more competitive wages and benefits.
In 2022 and 2023, PowerSchool Allovue worked with the EdWeek Research Center to poll U.S.-based educators. One finding was that regardless of role, educators tend to underestimate the monetary value of their benefits. It’s unclear if this is due to lack of knowledge—or if they value their experience of their benefits well below the true cost. Carefully consider which benefits are cost effective and highly valued by staff before assuming this marginal cost.
