In a world that is constantly changing, job stability can be hard to come by. Economic ebbs and flows can result in new business one moment and layoffs the next. There are a lot of ideas about how to imbed oneself into a company in a way that would secure longevity. Becoming a core part of an organisation can also result in a stronger position for negotiating compensation.

There are two main trains of thought. Some people try to be irreplaceable, while others focus on being indispensable. There is a very fine line between the two, but the outcomes are miles apart. What’s the difference?
I have often seen people carve out a role in which they become irreplaceable. Effort is spent becoming the ultimate master of their domain, and then making sure that they protect the information so no one else can do what they do. Maintaining control is key. The person puts themselves in a position where only they can do their job, leading to confidence about job security. It’s not easy and requires a lot of effort; it’s also not the best career move.
A situation where someone is irreplaceable also means that every time the person wants to take time off or engage in a new initiative, colleagues feel frustrated because no one else can address the work. At review time, the lack of a successor for the role could hinder a company’s interest in broadening responsibilities, and compensation for a static skill set is only going to increase to a certain point. If the technology or product changes in a way that no longer requires this specific skill set and the person has not demonstrated that they have anything else to offer the organisation, there is little reason for the company to retain the employee.
Being indispensable is a much stronger position. Become invaluable to an organisation, not just through tactical responsibilities but by contributing strategic value, are key to a company’s ongoing success. If you gain knowledge and skills for a particular role, share the expertise with colleagues and put yourself in a position to take on new responsibilities. This proves that you will continue to be relevant as the organisation evolves.
Instead of creating a domain based on control, you become a hub of information and ideas. When there is a new challenge to tackle, management will specifically seek out people who are able to work through issues in a positive way, learn new skills and share their knowledge. The school of thought is not about control. Instead, the focus is cultivating an environment of collective success.
