Sink or Swim Is Not a Training Strategy: Why New Managers Deserve Better

Becoming a manager for the first time is one of the toughest transitions in anyone’s career. One day you’re an individual contributor with clear tasks; the next, you’re expected to lead, coach, inspire, and deliver results through other people.

Unfortunately, too many organizations take a “sink or swim” approach to management. They promote high performers into leadership roles with little or no preparation, cross their fingers, and hope for the best. The result? Stress, frustration, and underperformance that ripples through entire teams.

According to a Gallup study, 60% of new managers fail within the first 24 months. That’s not a talent problem, it’s a training problem.

Let’s break down why the sink-or-swim method doesn’t work, what it costs organizations, and how to build a smarter strategy for developing leaders.

The Myth of “Natural Leaders”

There’s a common assumption that good employees automatically make good managers. But leading people requires an entirely different skill set than executing tasks.

• A top salesperson might know how to close deals, but that doesn’t mean they know how to coach others.

• A brilliant engineer may write clean code, but that doesn’t prepare them to motivate a diverse team.

Leadership isn’t instinctive, it’s a learned discipline. By skipping training, companies set new managers up for failure from day one.

The Hidden Costs of Sink or Swim

When organizations throw managers into the deep end, the consequences aren’t just personal stress. They’re organizational risks:

1. High Turnover: Poorly trained managers drive talent away. Research shows employees are 70% more engaged when they feel supported by their manager.

2. Team Burnout: If the manager is overwhelmed, the team feels it too. Work piles up, priorities get lost, and morale tanks.

3. Lost Productivity: Gallup estimates poor management practices cost U.S. businesses $360 billion annually in lost productivity.

4. Damaged Culture: A single struggling manager can create ripple effects of disengagement across multiple departments.

Put simply: sink or swim isn’t a cost-saving shortcut, it’s a growth killer.

Why Training Matters

Leadership is one of the most trainable skills in the workplace. With the right support, even first-time managers can thrive. Training provides:

• Clarity – Clear expectations of what good management looks like.

• Confidence – Tools for handling difficult conversations and decisions.

• Connection – Guidance on building trust and motivating diverse teams.

• Consistency – A shared language and approach across the organization.

Think of it like this: you wouldn’t expect someone to operate complex software without onboarding. Why expect someone to lead humans without preparation?

What Works Better Than Sink or Swim

The good news: there are proven alternatives to the sink-or-swim method. Here are some strategies that actually set new managers up for success:

1. Structured Onboarding for Leaders

Instead of throwing them in blind, create a leadership onboarding program. This could include shadowing senior leaders, training sessions on feedback, or even role-playing difficult conversations.

2. Ongoing Coaching and Mentorship

Pair new managers with an experienced mentor or coach. A trusted guide can provide perspective, answer questions, and model leadership behaviors.

3. Peer Learning Communities

Create forums where managers share challenges, swap strategies, and learn from one another. Leadership can feel lonely, community reduces that isolation.

4. Practical Training Modules

Break training into bite-sized, real-world modules:

• How to run one-on-ones

• Giving feedback that lands

• Managing time as a leader

• Setting goals and accountability

5. Feedback Loops

Encourage two-way feedback. New managers should receive constructive feedback from their teams, not just their superiors.

A Case in Point: Two Different Journeys

Imagine two employees promoted into management at the same time:

• Alex is told, “Congrats! Here’s your team. Good luck.” Within months, Alex is overwhelmed, avoids conflict, and loses two top performers.

• Jordan enters a program where they shadow a senior leader, attend training sessions, and get biweekly coaching. Jordan learns how to set expectations, build trust, and coach their team. Within months, Jordan’s team reports higher engagement and stronger performance.

The difference isn’t talent. It’s training.

Building Managers with Heart

At Manage With Hart, we believe leadership isn’t about throwing people into the deep end, it’s about giving them the tools, coaching, and confidence to thrive.

When organizations invest in their managers, they don’t just build better leaders, they build better teams, stronger cultures, and healthier businesses.

Key Takeaway:

Sink or swim is not a strategy. It’s a setup for failure. Equip managers with training, support, and mentorship, and you’ll see the difference ripple through every level of your organization.
