When you know you can rely on someone, you quickly start giving them more. Not because you want to overload them, but because you know the job will be done properly. If something is urgent, you give it to them. If something needs to be finished quickly, you turn to them again. If someone else needs help, you already know who you will ask first.
At first, that can even feel like recognition. The person receives trust, more responsibility and gets involved in important things. The problem starts when that becomes the rule.
Reliability can very easily turn into extra work
A good employee often does not need much supervision. You do not need to remind them, they know the priorities and they deliver what was agreed. That is exactly why it can very easily happen that, alongside their own work, they start picking up things that have fallen somewhere in between.
Someone did not get to it? Give it to them. Someone is not confident enough yet? Let them help. A new project has appeared? They will figure it out.
Each individual decision may make sense. It is only when you look at them together that you realise the person who does their job best is slowly getting the largest share of everything extra.
And that is where reliability can start to feel less like an advantage and more like a penalty.
The best people often will not be the first to say it is too much
That may be the biggest risk for me.
People we are used to seeing deliver will often keep the same pace for a long time. They will not necessarily say immediately that they are overloaded, they will not treat every extra responsibility as a problem, and they probably will not be the first to make a fuss about it.
That does not mean they do not care.
Sometimes the first thing you notice is that they are less involved, that they no longer offer ideas as they used to, or that they still do things properly but without the energy they once had. The result may still look good, which makes that change easy to miss.
That is why I do not think it is enough to look only at whether someone can take on something else. It is much more important to ask whether they should.
Not every additional responsibility is development
We like to say that we give someone more because we want them to develop. And sometimes that is genuinely true.
But there is a difference between giving someone a new challenge that brings new experience and simply adding more work because we know they will get it done.
If someone is constantly solving the same problems, covering for others and picking up what nobody else finished, that may increase their workload, but it does not necessarily mean they are developing.
Development should bring something new: greater autonomy, a different kind of responsibility, an opportunity to learn something or a chance to influence the broader picture. If the only change is that a good employee now works more than before, it is difficult to call that development.
Sometimes the problem is that we are not developing the rest of the team
If the same people always take on the more demanding work, they keep getting better, but the rest of the team does not get the opportunity.
In the short term, it is easier to give the task to someone you know will do it well. In the long term, that can create an even bigger gap between a few very strong people and everyone else.
Then we go back to the same people again because they are the only ones who can handle the more complex situations.
That can very easily become a cycle that is difficult to break.
Sometimes it is slower and less comfortable for a manager to give the work to someone who cannot yet do it perfectly, but that is exactly how a broader and more stable team is built.
Good people need to feel that their contribution is seen
I do not think good employees should be protected from every additional task. Often they are exactly the people who want more responsibility and want to be involved in things that matter.
But there is a big difference between someone getting more because they are progressing and getting more simply because they always say yes and get the job done.
If we constantly expect more from someone, it is only fair to talk about what they are getting in return. I do not necessarily mean only a title or salary. For some people it is development, for others greater autonomy, recognition, or simply the feeling that they have not become the person every problem is automatically passed to.
That cannot be assumed. It needs to be discussed.
I would not only ask a good employee whether they can take on more
Increasingly, the more important questions for me are what the person is already carrying, which parts of it still make sense to them and what their next step should be.
Because if we keep giving our best people more simply because we know they can handle it, we may get excellent results for a while. But we can also easily reach the point where someone who has long been among the most engaged people decides they no longer want to be the person who can always do everything.
Reliability should bring more trust and development, not just more work.
