Sub This Work Out or Hire a W2 Employee: Decision Tree
Why this matters
The most expensive staffing mistakes are structural, not personal. Sub out work that is really your steady, core load and you bleed margin every week to another company's markup. Hire a W2 employee (a payroll worker whose wages you report on a W-2 and for whom you withhold taxes) to cover a short spike and you pay idle labor the moment the spike ends. This choice is a make-or-buy decision, and making it on gut in a busy week is how shops end up over-committed one way or the other.
This tree is the strategic call: should this work be subbed out or staffed in-house. It is separate from the legal question of whether a given person is a contractor or an employee, which is a test you do not get to choose (see the related classification articles). Decide the strategy first, then respect the law on how you engage whoever you land on.
Start here: is the demand steady or a spike
One question sorts most cases.
- Is this work steady, recurring, and core to what you sell? Lean toward hiring.
- Is it a one-time overflow, a seasonal surge, or a specialty you do not offer? Lean toward subbing.
An employee is a fixed cost you carry in slow weeks and busy ones. That is a liability when demand is lumpy and an asset when it is steady, because a full-time worker you keep busy almost always costs less per hour of real output than a sub's all-in rate.
Walk the deciding questions
If the skill is outside your trade (you run electrical and the job needs a licensed plumber), sub it. Carrying a specialty wage you cannot fill with billable work is pure drag.
If you cannot keep the person busy year-round, subbing wins. A sub you call three times a quarter costs nothing between calls; an employee costs the same whether the phone rings or not.
If the work is your bread and butter and volume is climbing, hire. Every recurring job you sub out hands a slice of your own margin to someone else, and you never build the crew that lets you grow.
If you need control over how, when, and in what order the work is done, that pushes toward an employee. Directing a true sub's methods and hours undercuts their independent status and can turn them into an employee in the eyes of a tax or labor agency, whatever your paperwork says.
If you need to scale up fast without a long ramp, a proven sub crew deploys quicker than a hire you have to recruit, train, and license. But a sub crew you lean on constantly is a steady cost dressed up as a variable one, and a signal you have outgrown subbing that line of work.
Sub vs hire at a glance
| Dimension | Subcontractor | W2 employee |
|---|---|---|
| Cost pattern | Variable, pay per job | Fixed, paid in slow weeks too |
| Speed to deploy | Fast if pre-vetted | Slow (recruit, train, license) |
| Control of method and schedule | Limited by law | Full, you direct the work |
| Idle-time cost | None | You carry it |
| Tools and insurance | They provide | You provide |
| Loyalty and retention | Low, works for others | Higher, builds your bench |
| Best for | Spikes, specialties, overflow | Steady core volume |
When to pick which
- Pick a sub for overflow you cannot staff, a trade you do not carry, a distant one-off, or to test demand in a new service before you commit to a hire.
- Pick an employee for work that is core, recurring, and controllable, when volume can keep them productive, and when you want the quality and loyalty that only come from your own crew.
- The hybrid most shops land on: a lean core of employees sized to your reliable baseline of work, plus a short bench of vetted subs for the peaks. Staff the valley, sub the spike.
If you find yourself subbing the same core work month after month, the decision has already made itself. That is a hire waiting to happen.
