How to avoid HR disasters: a practical guide

When HR fails, it rarely stays internal. Poor people management can blow up into lawsuits, shareholder revolts, reputational damage—and, in extreme cases, even Royal Commissions. 

The worst part (or the best, depending on how you look at it)? Most of it is preventable.

Australia’s most famous HR nightmares of the past few years offer loud-and-clear lessons for any business that cares about culture, compliance and credibility. Here are five infamous case studies—and what they teach us all about how to lead, hire and manage better.

1. PwC Australia: Culture eats strategy for breakfast

The disaster

In 2023, PwC Australia was rocked by revelations that a senior partner had leaked confidential government tax plans to clients. This led to a significant loss of trust, and the sale of PwC’s government consulting arm. 

Beyond the headline scandal, the deeper issue was cultural: the behaviour was allegedly known internally for years, but nothing was done about it.

What went wrong

Ethics were sacrificed at the altar of revenue. HR and leadership let toxic behaviours fester, especially when tied to high-performing rainmakers.

The lesson: Culture is built by what you tolerate.

• Create clear ethical guidelines—but more importantly, enforce them.
• Don’t give high performers a pass just because they bring in revenue.
• Build formal whistleblower protections and act on concerns early.
• Make sure HR has real independence and authority—especially when calling out leadership.

2. Seven West Media: When power and HR collide

The disaster

The public fallout from an affair between CEO Tim Worner and executive assistant Amber Harrison became a long-running HR and PR disaster. The company reached a confidential settlement with Harrison—then pursued legal action when she broke the silence. 

So what started as a workplace conduct issue spiralled into headlines, accusations of hypocrisy and a public trust deficit.

What went wrong

There were no clear boundaries around relationships in the workplace—especially involving senior executives. Channel Seven’s response seemed to prioritise corporate protection over accountability and discretion.

The lesson: Workplace rules must apply to everyone—even the boss.

• Set clear, enforceable policies on workplace relationships, particularly where there’s a power imbalance.
• Prioritise transparency, not damage control.
• Avoid being heavy-handed with legal action unless it’s absolutely necessary—public perception matters.
• Make sure HR is empowered to deal with executive conduct, not just middle management.

3. Qantas: The cost of cutting corners

The disaster

In the wake of COVID-19, Qantas laid off and outsourced 1,700 ground crew—only for the High Court to later rule the move illegal. This followed a pattern of deteriorating staff morale, customer service issues, and a broader perception that the airline had lost touch with its people.

What went wrong

Short-term cost-cutting trumped people strategy. HR became reactive, not proactive and—while Qantas was hit hard by the pandemic—decisions were made with little regard for long-term consequences.

The lesson: Your people aren’t a line item.

• Understand that restructuring has cultural and operational consequences beyond immediate savings.
• Involve HR early in any change process, not just as the cleanup crew.
• Outsourcing should be a strategic choice (and sometimes it can be a great one), but it shouldn’t ever be a panic move. 
• Respect legal obligations, especially around redundancy and union engagement.

4. AMP: Reputation is the real bottom line

The disaster

AMP promoted Boe Pahari to CEO of AMP Capital, despite a prior sexual harassment complaint. The move triggered internal backlash, investor pressure and a rapid loss of trust. Pahari was removed from the role within weeks.

What went wrong

Leadership failed to anticipate how the appointment would land—internally, externally and ethically. HR red flags were ignored in favour of maintaining the status quo.

The lesson: What you reward defines you.

• Conduct matters—especially in leadership appointments.
• HR must have a seat at the table when it comes to promotions and succession planning.
• Don’t underestimate employee and shareholder expectations on ethics.
• If you make a misstep, fix it fast. Delay only deepens reputational harm.

5. Commonwealth Bank: When culture turns toxic

The disaster

The Banking Royal Commission uncovered widespread misconduct in CBA’s financial advice businesses, from charging fees to recommending incompatible products, and from dead customers to systemic failures in risk and compliance. While much of the focus was on financial conduct, HR was part of the failure—especially in failing to build a culture of accountability and ethical behaviour.

What went wrong

A culture of profit over principles took hold. Staff were incentivised to hit sales targets at the expense of compliance, and internal warnings were often overlooked.

The lesson:

Culture isn’t soft—it’s structural.

• Align performance metrics with values—not just dollars.
• Treat internal reporting as a health check, not an inconvenience.
• Regularly review incentives, performance frameworks and leadership behaviour.
• Culture audits aren’t just for show—take them seriously and act on what you find.

In short…

HR failings may start in private but they often end in very public outcomes. From lost trust to legal risk, the fallout can reshape companies—and careers.

The common thread in every one of these disasters? Warning signs were missed, minimised, or ignored. 

Bad culture isn’t just a people problem—it’s a leadership failure. And when leaders sideline HR, or treat it as an afterthought, they create blind spots that can turn into headlines.

The good news? Most of this is preventable. If you:

• Empower HR to act independently
• Set and enforce clear standards for conduct
• Link culture to performance—not just profit
• Take early warning signs seriously

…you’re not just avoiding disaster. You’re building a business people want to be part of.

Because in the end, culture isn’t what’s written on the walls—it’s what you walk past.
