Your company has 150 employees. You don't have a dedicated HR function. Your CEO handles compensation decisions. Finance processes payroll. Managers field employee questions ad-hoc. You've never had a compliance audit. You think you're saving money.
You're hemorrhaging it.
The cost of HR outsourcing gets framed as an expense. The absence of HR is a far more expensive gamble — the exposure accumulates quietly in turnover, compliance penalties, and lost productivity, and it can be estimated. A single wrongful dismissal settlement can run well into six figures. OHSA prosecutions carry heavy fines. A bad hire costs roughly 30% of first-year salary, per U.S. Department of Labor data.
Let's calculate your actual exposure. The worked examples below are illustrative models — swap in your own numbers. Our HR services practice builds the embedded HR infrastructure that reduces these exposures.
The Cost Calculator: Five Cost Categories
1. Turnover Costs
The formula: Annual turnover rate × number of employees × cost-per-hire (CPH)
Cost-per-hire: SHRM data (2024–2025) suggests CPH ranges from 50% to 200% of an employee's annual salary, depending on seniority. Use these benchmarks:
- Individual contributor (IC): 50%–100% of salary
- Manager: 100%–150% of salary
- Senior/specialized role: 150%–200% of salary
Why turnover is expensive: When an employee leaves, you lose productivity during their notice period, spend time recruiting, interviewing, and onboarding, and lose institutional knowledge and client relationships. It can take a replacement many months to reach equivalent productivity.
Illustrative example (adjust the assumptions to your own numbers): You have 150 employees. 20% annual turnover = 30 departures. Average salary is $85K.
- 20 ICs at 50% CPH = 20 × $85K × 0.5 = $850K
- 8 Managers at 125% CPH = 8 × $95K × 1.25 = $950K
- 2 Senior roles at 175% CPH = 2 × $120K × 1.75 = $420K
- Total annual turnover cost: $2.22M
Without HR, turnover tends to run above what stable, well-managed companies see. Poor onboarding, misaligned hiring, weak management, and lack of career pathing all drive attrition.
2. Compliance Penalties
Ontario ESA violations: Fines have increased sharply under recent Working for Workers amendments — see our Q1 2026 compliance checkpoint for the current figures. Common violations include:
- Failure to provide written notice or pay in lieu on termination
- Underpayment of overtime or minimum wage
- Failure to pay accrued vacation on termination
- Misclassification of employees as contractors
Ontario OHSA violations: Fines for corporations — and for officers and directors personally — can reach seven figures, with imprisonment also available; confirm current maximums under section 66 of the Act. Common violations include:
- Failure to maintain a workplace violence/harassment policy (Section 32)
- Failure to investigate reported safety violations
- Failure to report serious injuries to the Ministry
AODA violations: Administrative penalties that escalate with organization size and severity — confirm the current schedule under the AODA.
Pay Equity Act violations: Back-pay plus interest and potential fines.
Probability: The Ministry of Labour runs proactive inspection campaigns year-round. If you employ 150 people, your odds of an inspection in a multi-year window are material, especially if you're in construction, manufacturing, or any industry with hazard exposure.
Cost scenario: Even a modest OHSA penalty, a single wrongful dismissal claim, or an unaddressed pay equity gap can each produce five- or six-figure liabilities once legal fees and back-pay are counted.
3. Bad Hires
The formula: Number of bad hires × cost-per-bad-hire
Cost-per-bad-hire: 30% of the employee's first-year salary (U.S. Department of Labor). This includes lost productivity, hiring costs, separation costs, and replacement hiring.
Illustrative example: At 150 employees with 20 annual hires, assume 2–3 bad hires without structured hiring. At an average salary of $85K:
- 2 bad hires × $85K × 0.3 = $51K annually
Structured hiring (job descriptions, competency-based interviews, reference checks, trial periods) materially reduces bad-hire rates. Without HR, you're hiring on gut feel and referral, not rigor.
4. Litigation
Wrongful dismissal: Outcomes vary widely with tenure, age, role, and circumstances — many claims settle for months of pay plus benefits, with legal fees on top.
Human rights complaints: Awards and settlements at the Human Rights Tribunal of Ontario vary widely, and defence costs accrue regardless of outcome. Many are preventable through properly scoped workplace investigations at the complaint stage, before a grievance escalates to a tribunal filing.
Probability: If you employ 150 people and have no documented HR policies, performance management, or accommodation processes, your risk profile is high. Over a 5-year period, the odds of a dispute escalating to litigation are material.
Cost scenario: One contested wrongful dismissal case generates substantial legal fees before any settlement is counted; the combined bill can climb well into six figures.
5. Productivity Loss and Disengagement
The formula: Rough estimate using Gallup data: disengaged employees operate at 18% lower productivity than engaged peers.
Cost calculation: Number of disengaged employees × salary × 0.18
Why this matters: Without HR, people don't feel supported, they don't understand career paths, they don't receive feedback, and they disengage.
Employees at growth-stage companies frequently cite a lack of clarity on advancement. Disengagement stays invisible until you see turnover spike.
Illustrative example: At 150 employees, assume 40% disengagement for the model — that's 60 people operating below capacity.
- 60 employees × $85K average salary × 0.18 = $918K in annual lost productivity
Total Exposure Calculation
Using the illustrative scenarios above, a 150-person company without dedicated HR faces:
- Turnover: $2.22M (assumes 20% turnover, above-market cost-per-hire)
- Compliance penalties (annualized over 3-year risk window): $100K–$200K
- Bad hires: $51K
- Litigation risk (annualized over 5-year window): $40K–$60K
- Productivity loss: $918K
Total annual exposure: $3.33M–$3.45M
This is aggregate modelled risk, not a per-person invoice — and every input is adjustable. Plug in your own turnover, salary, and hiring numbers. Many high-growth companies see higher turnover and worse hiring outcomes than the assumptions above.
The Cost of a Solution
Covering this scope in-house realistically takes a dedicated HR Director plus an HR Manager or Coordinator — a low-to-mid six-figure annual commitment once salary, benefits, and tools are counted.
A Part-Time HR mandate is scoped to the employer's needs, practitioner availability, responsibilities, time commitment, and exclusions. 1205 confirms those elements after fit review.
Comparison:
- No HR: millions in modelled hidden costs at this headcount
- Internal HR: multiple full-time salaries plus benefits and tools
- Outsourced/embedded HR: typically a fraction of the fully loaded cost of building every role in-house
ROI: In the model above, a single percentage point of turnover reduction saves six figures annually. A single avoided wrongful dismissal claim or OHSA penalty can cover much of the annual investment on its own.
Run the model with your own numbers — at this headcount, even modest improvements in turnover and hiring outcomes move six-figure amounts.
Why Growth-Stage Companies Skip HR
"We're lean. HR feels like overhead."
This logic breaks at scale. What works at 30 employees (founder-driven, ad-hoc) collapses at 150. The pain points (high turnover, compliance gaps, poor hiring, weak onboarding) accumulate invisibly until they explode.
The best time to invest in HR was when you hit 50 employees. The second-best time is now.

We'll conduct a confidential HR diagnostic: audit your compliance exposure, review your hiring outcomes, quantify your turnover costs, and build a roadmap for sustainable people operations. The cost of the diagnostic is far less than a single compliance penalty or bad-hire cycle. Contact 1205 Consulting.
