I have seen people join organisations with a clear understanding of why they were hired. The role has a defined purpose. The responsibilities make sense, and the person can see how the position connects to the career they hope to build. They arrive with energy, ambition and a strong sense of direction.

Then the role begins to expand.

At first, this often feels positive. New responsibilities bring new knowledge. The person learns how other departments work, becomes involved in unfamiliar processes and gains a wider understanding of the business. Much of this can be valuable; knowledge rarely goes to waste, and exposure beyond one's original function can make someone more capable and more rounded.

The difficulty begins when the responsibilities keep growing, but the direction does not.

A person may become useful in many areas while slowly losing a clear sense of where they belong. They are asked to solve different problems, support different teams and carry work that was never part of the role they originally accepted. From the outside, this may look like trust: the organisation sees someone dependable, adaptable and willing to help. Inside, however, a quieter question begins to form.

What exactly do I do now?

It is a difficult question when the answer has become too broad. The person remains busy and relied upon, yet may struggle to explain what their role has become or where it is leading.

They are present everywhere, but fully placed nowhere.

Over time, this can affect confidence. Someone who once had a clear professional identity may start wondering whether they are still developing in their original field or simply moving between responsibilities. The experience they have gained should make them feel stronger. Instead, the lack of direction can make them doubt where their real value now lies.

There is also a less visible risk: familiarity can gradually become a trap. The person understands the organisation, knows how work really gets done and has become difficult to replace. That usefulness creates security, but it can also make movement harder. The longer the role remains undefined, the more difficult it can become to explain that experience outside the organisation.

This is not always a comfort zone. The person may not feel comfortable at all. They may simply feel too embedded to leave, and too uncertain to know what should come next.

Organisations also carry responsibility here. When capable people are repeatedly moved into unrelated areas, the business gains flexibility. But unless the role is periodically redefined, the employee may gain more work without gaining a clearer position, a development path or a professional identity. What appears to be growth for the organisation may quietly become drift for the individual.

This does not mean every responsibility outside a job description is harmful. Some of the most valuable learning comes from work that was never planned, and roles must change as organisations change. The concern is not change itself. It is change without clarity.

A person can continue learning, solving problems and adding value for years while becoming less certain about the future they are building.

Sometimes the greatest career risk is not failure or a lack of opportunity. It is becoming so useful everywhere that you no longer know where you belong.
