Successful workers are no longer defined by their ability to hone one specific set of skills and apply it throughout a linear, one-company career. Instead, the most successful workers are those with "liquid skills" – the ability to upskill, reskill and continuously hone existing capabilities. These workers accept that their current expertise could be outdated in the near future, and they will therefore continuously seek to acquire new, relevant skills. Certainly in a start-up culture we see the modern worker offering an organization a diverse range of skills, which are used to fill specific skills gaps. Within a single tenure at one particular organization, a worker can expect to bounce from role to role, meeting different skillset needs at different times, effectively having multiple careers without leaving the company.
