TOWARD AN ORGANIZATIONAL BEHAVIOR OF CONTRACT LABORERSTHEIR PSYCHOLOGICAL INVOLVEMENT AND EFFECTS ON EMPLOYEE CO-WORKERS.

You are an engineer. You show up every day, you know the culture, and you cover for teammates when things go sideways. Then one day, a contractor sits down next to you — same desk, same project, and same coffee machine — but a completely different deal. Higher hourly pay, no benefits, and gone in six months. The question Jone Pearce set out to answer isn't what that does to the contractor. It's what it does to you. That inversion is the engine of this research. And the findings are not what the theory predicted. Pearce grounds the study in what economists call the markets versus hierarchies debate. This idea, developed by Ronald Coase and Oliver Williamson, suggests that firms choose between two ways of getting work done: they hire employees and manage them through internal structures, or they contract for labor in the open market. Most economic analysis treats those as interchangeable options with different price tags. Pearce asks whether they're actually interchangeable at the human level. Her central concept is what she calls quasi-moral involvement — a worker's sense of genuine psychological obligation to the organization, expressed through two measurable things: organizational commitment, meaning identification with and attachment to the firm, and extrarole behavior, meaning citizenship acts that go beyond the job description, such as helping coworkers learn procedures, taking initiative on problems, and pitching in when deadlines loom. The theory, following Williamson and others, says employment contracts cultivate quasi-moral involvement while market contracts produce something colder and more calculated. Pearce wanted to test that directly. She also wanted to know whether having contractors nearby reshapes what employees feel and do. The setting was a large aerospace company in southern California, engineering-heavy, building equipment for both commercial aircraft manufacturers and federal contractors. Contract labor wasn't exotic here; it was routine. Contractors wore differently colored badges and were seen as a real career alternative. The firm used them to absorb industry fluctuations. Pearce surveyed all engineers and engineering technicians across three divisions, collecting questionnaires in group settings and matching responses to personnel records. Of two hundred eighty-four potential respondents, two hundred twenty-three returned usable surveys — an eighty-four percent response rate for employees and fifty percent for contractors. Twenty-five of thirty-three supervisors also participated, providing independent performance ratings. The final dataset contained one hundred ninety-nine employees and twenty-four contractors. Within the employee group, fifty worked in units where their supervisor had at least one contractor report, while one hundred fifteen worked in employee-only units. That contrast — mixed units versus employee-only units — is where the most important findings reside. The pay gap was sharp and visible. Contractors earned a mean of twenty-seven dollars and sixteen cents an hour, while employees earned nineteen dollars and twenty-six cents. Contractors had shorter tenure, averaging seventeen months, and less job security. About forty-five percent came through employment agencies, while fifty-five percent were self-referred. Everyone in the building could see the badge colors. Now to what the data actually showed about contractors themselves, because here the theory runs into trouble almost immediately. Pearce's first two hypotheses predicted that employees would show greater quasi-moral involvement than contractors. This meant more extrarole behavior and higher organizational commitment. Neither held up. Contractors self-reported significantly more extrarole behavior than employees. Supervisors, rating cooperativeness as one of five performance dimensions, saw no difference between the two groups. And on organizational commitment — the psychological attachment measure — there was no significant difference either. The expected gap simply did not appear. Pearce found this genuinely surprising, and she offers two interpretations worth considering. First, contractors in these work units faced immediate social pressure from the team around them. In interviews, contractors described a tension between the contractual expectation of limited involvement and the social reality of wanting to fit in; they tended to adopt team behaviors rather than risk ostracism. Second, employees may actually undercount their own citizenship acts because so many of those acts have become invisible — absorbed into the baseline of what the job is, rather than perceived as extra. Contractors, newer to the norms, notice the acts as distinct. Pearce is careful about the limits here: twenty-four contractors is a small sample, and nonsignificant results don't prove equivalence. But the hypothesis that employment produces more quasi-moral engagement than contracting found no support in this data. So, if the contractors themselves aren't the story, what is? The employees are. And this is where Pearce's findings get sharper. Employees in units with contractor coworkers reported lower organizational trust than employees in employee-only units. That's the fourth hypothesis, and it was supported. The mechanism Pearce proposes runs through fairness and signaling: when an employee sees a contractor doing similar work for higher hourly pay, fewer benefits, and no real security, that contrast signals something about how the organization views the employment relationship. It suggests the firm is acting more like a market participant than like a party to a long-term, reciprocal arrangement. That signal, Pearce argues, makes employees question whether the organization will deliver on its tacit obligations — and reduced trust is the measurable result. There's also a task reallocation effect, though the evidence here is more mixed. Pearce predicted that supervisors would shift interdependent work — tasks that require coordination and ongoing accountability — away from contractors and onto employee coworkers. Task interdependence was measured with three scales covering dependence on others, others' dependence on you, and reciprocal interdependence. Employees in mixed units reported significantly more dependence on others and marginally more others-dependence on them, but reciprocal interdependence didn't differ significantly. Pearce calls this weak support for the hypothesis. She supplements it with interview accounts that make the mechanism concrete. Supervisors described deliberately giving contractors simpler, easier-to-monitor tasks. One said he had been "burned by contractors" when problems surfaced after they had left and concluded he needed to supervise contractors more closely and protect downstream work by keeping it with employees. The practical consequence is that employee coworkers absorb more of the connective tissue of the project: the coordination work, the things that require continuity. Put those two findings together — reduced trust and increased coordinative burden on employees — and the picture that emerges is uncomfortable. The firm adapted structurally, assigning interdependent work to employees so contractors could be given bounded, monitorable tasks. That adaptation served the organization's short-term interests. But it redistributed costs onto the employees who remained, leading to more work requiring coordination and less confidence that the organization would hold up its end of the deal. That is not a neutral transaction. Pearce is explicit about the study's limits. It involves a single firm, a single sector, a cross-sectional design, and a small contractor sample. These findings are suggestive, not definitive, and she flags each of those constraints. She also highlights what the literature has been neglecting: the supervisory cost. Managers in mixed units face different and more demanding oversight responsibilities than those running employee-only teams, and that burden had barely appeared in organizational research before this study. What makes this work matter beyond its specific findings is the framework Pearce builds around them. The economic argument for contract labor is about cost. The cost goes down on the firm's side because you pay contractors for time and output without the overhead of long-term employment. Pearce's data suggest that framing is incomplete. The costs don't disappear — they redistribute. They show up as extra coordinative load on employees who stay, as supervisory strain on managers overseeing mixed units, and as reduced trust in an organization that has made its market logic visible. Contractors earned roughly forty percent more per hour than employees and had an average tenure of seventeen months. Employees who worked alongside them trusted their organization measurably less than those who didn't. The gig economy has only expanded since Pearce published this work, making the research more relevant, not less. Contingent labor arrangements, such as contractors, freelancers, and platform workers, are now routine in sectors far beyond aerospace engineering. The dynamics Pearce documented in one California firm are playing out at scale. When organizations treat labor as a market transaction, someone still has to hold the long-term knowledge, absorb the coordination costs, and live with what the arrangement says about how the firm sees them. That someone is the employee sitting next to the differently colored badge. This lecture was created by ennepō.
