The Rise of the “Accidental Manager” and Its Impact on Team Effectiveness

The Rise of the “Accidental Manager” and Its Impact on Team Effectiveness

 

Have you ever been on a team where the top performer was suddenly thrust into a management role? Or maybe you were asked to “look after” your team while your manager was on vacation? Both of these are examples of accidental managers: individuals moved into leadership positions without any formal progression, training, or development.

Organizations may think this is a quick win. After all, they just sourced a management professional without all that tedious and expensive managerial recruitment. However, there are multiple hidden costs to accidental managers, from productivity to turnover. 

Poor Productivity and Performance

Just because someone excels at their individual role does not mean they are qualified to lead a team of people performing similar tasks. Yes, they probably know the best way to get the job done and how to prioritize tasks effectively. But do they know how to mediate inter-team conflicts, liaise with senior management, or collaborate effectively with other areas of the business?

Unless the individual has previous managerial experience, it’s doubtful. Accidental managers are more likely to drive poor employee engagement and negatively impact morale than an experienced manager. They don’t know how to promote productivity and manage performance, and this has a direct effect on employee retention. Statistics from the UK show that:

  • Around 82% of managers haven’t had formal leadership training
  • Half of surveyed workers who consider their manager “ineffective” are planning to leave their companies within a year
  • Conversely, companies with formal leadership development programs see better employee engagement and retention

Firms that ensure their managers understand how to lead people effectively meet their business goals and objectives sooner, while spending less on recruitment and retraining. 

Identifying Management Development Gaps

If you find that your organization is frequently relying on enthusiastic but underqualified professionals to lead teams, you could have some serious management development gaps. Perhaps your existing management training programs aren’t accelerating fast enough, meaning you have more management roles empty than people to fill them. Alternatively, perhaps employees aren’t motivated or incentivized to start the leadership development process, which could indicate deeper problems within your organizational culture. 

For some firms, it can simply be that the leadership training isn’t sufficient. Managing people requires empathy, organizational knowledge, delegation skills, and the ability to mediate. If one or more key managerial skills are missing from the training program, leaders will enter roles unprepared for the challenges ahead.

Consider the following questions to identify management development gaps:

  • Do managers thrive or struggle in their current environment?
  • How effectively do they communicate with their teams and leaders?
  • Are they transparent about the challenges they’re facing?

Gathering feedback from team members can help businesses better understand the effectiveness of their managers, before problems begin to impact employee turnover. 

Strategies to Mitigate the Effects of Accidental Managers

Leadership effectiveness challenges range from poor time management to a lack of people skills. However, for accidental managers, these problems are rarely the manager’s fault. They’re more likely the result of ineffective training and poor expectation setting by their own leaders.

Organizations can mitigate problems like these by implementing processes that prevent the rise of accidental managers. For example, if someone is expected to “step up” to lead a team in their manager’s absence, this person should have a buddy or mentor to support them. Ideally, they should also be enrolled in the company’s management development program, with clear goals and objectives set.

Fostering a culture of continuous learning and mentorship increases employee engagement and loyalty. Businesses are showing that they’re genuinely invested in the future of employees and the success of their long-term career goals. 

Formal management development programs also attract individuals who want to manage, rather than forcing talent into roles they may not be ideally suited for. 

Invest in Effective Leaders

The accidental manager appears across multiple industries, but it’s a strategy that’s rarely an effective way to find competent, long-term leaders. It’s an example of businesses reaching for the nearest, most convenient succession planning solution, rather than sourcing talent who will contribute to long-term business growth. Avoid reduced team productivity and tanked morale by investing in effective management recruitment practices or leadership development programs.
