Why do digital departments have such a high employee churn rate?

Is it because the young people who are hired to work in digital departments are building their career and are able to use each job as a stepping stone to the next position?

Is it because the reward and recognition package offered by the organisation doesn’t match the expectations of the people?

Is it because the structure and nature of the organisation doesn’t match the desire for creativity, self-expression and independence of these people?

Is it because digital is a fast-moving industry so staying on a position for less than a year is considered normal?

And is it a problem? Of course each recruitment costs the organisation, but what if a person in a role for six months provides enough value to the organisation that in fact it’s worth it for both parties.
