A bad hire on a piece rate crew is more expensive than most contractors realize, and a lot more expensive than a bad hire on an hourly crew. The reason is structural. On hourly, the cost is bounded by their hourly wage. On piece rate, the cost leaks into make-up pay, callback rework, the producers around them, and the foreman's attention. By the time you let them go, you've usually paid two or three times what you think you have.
This article walks through the buckets, runs a 90-day worked example, and then covers how to spot a bad hire in week one so you stop the bleeding fast.
My background is in roofing, gutters, and soffit and fascia. On a four-person roofing crew, one weak hire is acutely painful. They drag the whole crew's daily square count down, they create callbacks on flashings and details, and the strong installers next to them get frustrated and start asking why the slow guy is on their crew. The numbers below are what I wish I'd had in front of me earlier when running roofing crews.
Why piece rate amplifies a bad hire
The basic mechanics:
- You still owe minimum wage. Federal FLSA and most state laws require that piece rate workers earn at least minimum wage for all hours worked in the workweek. If the bad hire's piece output doesn't cover minimum wage, you write a make-up check. You're paying for hours worked but getting little to no installed labor in return.
- They slow producers around them. A bad installer on a roof creates work for the good ones. Re-doing flashings, finishing what they started, double-checking nail patterns. Your top producer's daily square count drops while the bad hire is on their crew.
- Callbacks land on your bid, not theirs. When a bad piece rate hire's work fails inspection or fails a year later, you eat the rework. They got paid for the install. You pay again to fix it.
- Crew morale is fragile. Piece rate crews self-police. The good ones notice when a slow guy is collecting full days at the job site while they carry the load. If you don't move quickly, you risk losing the producer, not the bad hire.
Hourly hides some of this. Piece rate puts it all on the paystub.
The cost buckets, itemized
Here's how I'd break out the actual cost categories. Pick numbers that match your shop, but the buckets are universal.
Bucket 1: Wages paid for low output
If your shop's average producer puts up 25 squares a day at $65 a square, that's $1,625 per day in installed labor. A bad hire putting up 8 squares a day generates $520. They're working a full day. You're paying them a full day. The gap between what they cost and what they produce is roughly $1,000 a day in lost installed labor capacity.
Over a 30-day month, 20 work days, that's $20,000 in capacity gap if they fully occupy a slot.
Bucket 2: Minimum-wage make-up pay
Federal minimum wage is $7.25; most states are higher. Take a state with a $14 minimum. A 40-hour week at $14 is $560 in guaranteed minimum-wage pay. If the bad hire's piece earnings only come to $380 that week, you owe $180 in make-up pay on top of the piece earnings. That's pure overhead with nothing produced.
Over 90 days, conservatively, $1,200-$2,500 in make-up pay is realistic on a chronically low-output hire. Run the numbers honestly with your state's minimum and your shop's piece rates using a minimum-wage calculator before you assume the make-up exposure is small.
Bucket 3: Payroll burden on wasted wages
Every dollar of wages you pay carries a burden: FICA (7.65%), federal and state unemployment, workers' comp (high in roofing, often 10-30% of payroll), and any benefits load. A reasonable burden multiplier for a roofing piece rate hire is 1.25-1.40x.
So that $1,200-$2,500 in make-up pay isn't really $1,200-$2,500. It's $1,500-$3,500 once you load it up. And every dollar of low-output piece pay carries the same multiplier. This is why the fully-burdened labor rate matters more than the headline rate when you're costing out a bad hire.
Bucket 4: Callbacks and rework on their work
This is the bucket that hurts the most because it shows up after they're gone.
A roof installed wrong doesn't always fail in week one. Step flashings done sloppy, drip edge tucked behind the underlayment instead of in front, valleys closed wrong. The customer calls in 8 months when the leak shows up. Now you're sending a crew back. Tear-off and rework on a single roof can run $2,000-$8,000 depending on the damage.
If your bad hire was on three jobs over their tenure and one of them comes back as a callback, you've burned the equivalent of a month of their wages just to fix one of their installs.
Bucket 5: Top producer slowdown
A good roofer next to a bad one slows down. They have to fix mistakes, they double-check the bad hire's nail patterns, they redo flashings. Realistically, a top producer paired with a bad hire loses 15-25% of their daily output.
If your top producer normally puts up 35 squares a day at $65 a square, that's $2,275/day in installed labor. A 20% slowdown costs $455/day. Over 30 days, that's $13,650 in lost top-producer capacity that you can directly attribute to the bad hire being on the crew.
This is the bucket most contractors miss because it's invisible on the bad hire's paystub. It's only visible when you look at what your top producer used to put up versus what they're putting up now.
Bucket 6: Foreman attention
Your foreman or lead installer spends extra time on a bad hire: re-explaining the same details, checking their work, doing the parts they can't be trusted with. A foreman pulled into babysitting is a foreman not running the rest of the crew.
Conservatively, 4-8 hours a week of foreman time at $40/hour loaded is $640-$1,280 a month in foreman opportunity cost.
Bucket 7: Opportunity cost of the slot
Maybe the most painful bucket. The slot the bad hire is in could have been filled by a solid hire. If a solid hire produces $1,500/day and a bad hire produces $520/day, you're losing $980/day in capacity just by having the wrong person in the chair.
Over 60 days before you finally let them go, that's $58,800 in lost capacity you'll never recover. The slot was occupied. The work didn't get done. Your competitor took the next bid because you couldn't staff up fast enough.
Bucket 8: Crew morale and turnover risk
When a top producer watches a bad hire collect a full day's pay for half-day output, they start running their own math. They wonder why they're carrying the slow guy. If you don't act, they sometimes start looking. Losing a top producer because you wouldn't fire a bad hire is the worst case in this entire article.
This bucket is hard to dollar-value, but retention research puts replacement of a top producer at $8,000-$15,000 minimum. Multiply that by the probability the bad hire is causing your top guy to look around. Even at a 10% probability, that's $800-$1,500 of expected loss layered on top of everything else.
A 90-day worked example
Here's a conservative scenario for a single bad hire on a roofing crew, kept on the payroll for 90 days before termination. State minimum wage assumed $14/hr; piece rate $65/square; burden multiplier 1.30x.
| Cost bucket | 90-day cost |
|---|---|
| Minimum-wage make-up pay (loaded) | $2,800 |
| Top-producer slowdown (20% on one paired producer) | $13,650 |
| Foreman extra attention | $1,920 |
| Callback (one job comes back, mid-range) | $4,500 |
| Opportunity cost (slot occupied 60 days at $980/day before termination) | $58,800 |
| Crew morale / turnover risk (probability-weighted) | $1,200 |
| Recruiting and re-hiring to backfill | $1,500 |
| Total | ~$84,000 |
That's the realistic 90-day cost of one bad hire on a roofing piece rate crew. Even if you cut every bucket in half, you're at $42,000. The point is that nobody's "bad hire cost" is the $4,500 they took home in piece earnings. The damage compounds.
For comparison, SHRM's published research on bad-hire costs ranges from about $4,000 for entry-level roles to $240,000 or more for senior positions. A piece rate field hire sits in a middle band that's higher than people assume because of the make-up pay, callback risk, and producer-pairing slowdown.
How to spot a bad hire in week one
The good news: piece rate is honest. The numbers show up fast. You don't need 90 days to know.
Day-one to day-five output thresholds
Set a written threshold before they start. A reasonable rule:
- By end of day 3: at least 40% of crew average daily output.
- By end of day 5: at least 55% of crew average daily output.
- By end of week 2: at least 70% of crew average daily output.
If they're under those thresholds with no upward curve, you have a problem. New hires improve in week one. Bad hires plateau early.
Quality flags from the foreman
Ask the foreman three questions at end of day 3 and end of day 5:
- Are they listening when corrected?
- Do they make the same mistake twice?
- Would you want them on your crew if you were the lead?
Two no's, you have your answer. Document the answers.
Pace of improvement
A new hire doing 12 squares on day 1 and 18 squares on day 5 is on a healthy curve. A new hire doing 12 squares on day 1 and 13 squares on day 5 is flat. Flat is the warning sign, not the absolute number.
Callback flags from inspections
If the foreman or lead is finding nail patterns wrong, flashings sloppy, or drip edge installed backwards on day 2 and again on day 4, that's not a learning curve, that's a pattern. Fix it once, document it, fix it twice, document it, on the third you have a termination case.
How to handle the conversation when you cut them
Cut early, cut clean, cut documented.
- Pull the numbers. Print their daily square output, their make-up pay weeks, any callback flags from the foreman.
- Sit them down on a Friday afternoon. Walk through the numbers. Make it about output, not personality.
- Pay them through end of day, including any final make-up pay. No funny business on the last paycheck. That's how unemployment claims become wage-and-hour claims.
- Document the termination reason in writing. Performance, with the daily numbers attached. File it.
If you've been communicating piece rate clearly since day one, the conversation isn't a surprise. They knew the rate. They knew the average output. They knew where they stood.
Hiring better the next round
The cost of a bad hire is the case for slowing down hiring just slightly. Specifically:
- Trial day or trial half-day, paid. Watch them work. Roofing reveals bad hires inside 4 hours on a roof.
- Reference call to the last foreman, not the last HR contact. Foremen tell you the truth.
- Set rate output expectations during the interview. "On this crew, we expect 25 squares a day at full speed. New hires usually hit 70% of that by week two. Are you confident you can hit those numbers?" Watch their face.
- Onboard correctly. A structured onboarding for piece rate crews gets new hires productive faster and surfaces the bad hires sooner.
The point isn't to be paranoid. The point is that the cost of one bad hire is the same as 10-20 hours of better hiring process. That trade is obvious once you do the math.
Notes on the math
A few honest qualifiers on the numbers in this article:
- The opportunity cost bucket is the largest and the most contested. Some contractors argue you can't count what didn't happen. I'd argue you have to, because every day the bad hire is in the chair is a day the right hire isn't.
- Callback rates vary wildly by trade, by region, by crew quality. The $4,500 figure in the worked example is mid-range for residential roofing. Commercial, EPDM, and modified bitumen callback costs run higher.
- Burden multiplier varies by state and trade. Roofing workers' comp in some states is 25%+ on its own. Use a labor burden calculator to dial in your number.
- SHRM bad-hire cost ranges are widely cited; specific numbers shift by year and study. The order of magnitude has been stable.
Closing
The cost of a bad piece rate hire isn't their paycheck. It's the make-up pay, the callback rework, the slowdown of the producer next to them, the foreman time, the opportunity cost of the slot, and the morale damage to your top performers. Conservatively, $40,000-$80,000 over a 90-day window for a single bad hire on a small crew. SHRM's research backs the order of magnitude.
The fix isn't complicated. Set output thresholds in writing. Track daily output from day one. Listen to the foreman. Cut early, cut documented. Then put more energy into the front of the hiring funnel so you don't repeat it.
