Scaremongering or Hard Truth? | The Social Market Foundation (SMF) has found that your first job could be linked to a salary that’s 24% higher by your mid-thirties

The Social Market Foundation (SMF) recently released research suggesting that the quality of your first job can have a lasting impact on your career trajectory and earnings.

According to the report, individuals who start their careers in roles that support development, progression and skills growth can earn significantly more by their mid-thirties than those who begin in positions with limited opportunities to advance.

It’s an eye-catching finding. But is it really that simple?

Having worked with candidates and employers across a wide range of roles and industries, we’d argue that while the research highlights an important trend, the real lesson isn’t just about your first job. It’s about the environment you choose to develop in throughout your career.

What the Research Found

The Social Market Foundation identified a clear difference between what it describes as “accelerator” roles and “low-mobility” roles.

Accelerator roles are positions where employees are given opportunities to learn, take on greater responsibility and progress into more senior positions over time.

At the other end of the spectrum are low-mobility roles, where training, development and career progression opportunities are more limited.

The report also identified several career pathways that fall somewhere in between:

  • Accelerator pathways, which provide strong support, training and progression
  • Stepping-stone pathways, which are imperfect but still useful platforms
  • Comfort-trap pathways, which are stable but limiting
  • Underemployment pathways, where people feel overqualified or underused
  • Low-mobility roles, offering little support or development.

The central conclusion is clear: access to development opportunities early in a career can have a long-term impact on earning potential and professional growth.

The Salary Figure Isn’t the Most Important Part

The headline statistic understandably focuses on future earnings.

However, we believe that’s actually the least interesting takeaway. Salary is often the outcome of career development, not the cause of it.

The professionals who progress fastest aren’t always those who accept the highest-paying role at the start of their careers. More often, they’re the people who join organisations that invest in their development, challenge them with new responsibilities and expose them to experienced leaders.

In many cases, we’ve seen candidates accept slightly lower starting salaries in exchange for stronger progression opportunities, only to accelerate far beyond their peers a few years later.

That’s why evaluating a role purely on salary can sometimes be a mistake.

A £2,000 increase today may feel significant. But if one role provides structured development, mentoring and genuine opportunities to progress while another doesn’t, the long-term difference can be far greater.

What Actually Creates Career Acceleration?

One area where we think employers sometimes focus too narrowly is training. Training is important, but it’s only one piece of the puzzle.

The organisations that create the strongest career outcomes typically combine several factors:

  • Managers who actively coach and develop their people.
  • Clear progression pathways.
  • Opportunities to take on new responsibilities.
  • Exposure to senior decision-makers.
  • Internal promotion opportunities.
  • A culture that rewards learning and growth.

The best employers don’t simply offer development programmes. They create environments where development happens every day.

Equally, we’ve seen candidates become stuck in otherwise attractive roles because progression was never clearly defined. The salary was competitive, the team was supportive and the role felt comfortable, but after several years there was little opportunity to move forward.

That’s exactly the type of “comfort trap” highlighted in the SMF research.

Questions Every Candidate Should Ask

The challenge for job seekers is that it can be difficult to identify these opportunities from a job description alone. When considering a new role, it’s worth asking:

  • What does progression look like from this position?
  • How many people have been promoted internally in the last two years?
  • How is employee development supported?
  • What responsibilities have previous people in this role gone on to take?
  • How are managers expected to develop their teams?
  • Can the company share examples of successful career journeys?

The answers can often tell you far more about your future prospects than the advertised salary alone.

What This Means for Employers

The findings also contain an important message for employers.

Attracting talent is only part of the challenge. Retaining and developing that talent is increasingly what differentiates the best organisations from the rest.

Employees, particularly those earlier in their careers, are paying closer attention to progression opportunities, skills development and future employability.

Businesses that fail to provide those opportunities risk losing talented individuals to organisations that do.

The government’s recent focus on workforce development reflects a growing recognition that skills and progression are not simply employee benefits. They are critical drivers of long-term economic growth and business performance.

A Final Thought

The SMF’s findings should be a reminder that careers are rarely shaped by a single decision.

What matters most is not necessarily where you start, but whether you’re in an environment that helps you keep moving forward.

For candidates, that means looking beyond salary and considering the opportunities a role will create over the next three to five years.

For employers, it means recognising that development isn’t a perk. It’s one of the strongest investments you can make in both your people and your organisation’s future success.

At iMultiply, we’re fortunate to work closely with both candidates and employers, giving us insight into the environments where people genuinely thrive. The organisations that create the best long-term outcomes aren’t always those offering the highest starting salaries. More often, they’re the ones investing consistently in their people, providing opportunities to grow and creating clear pathways for progression.

And ultimately, that’s what turns a job into a career.
