  Since its inception, the Large Hadron Collider (LHC) has significantly
advanced particle physics and will continue to do so in the context of the High
Luminosity LHC (HL-LHC) program to collect $3000$ fb$^{-1}$ by the end of 2041.
The particle physics community worldwide is discussing which future collider
could follow in the footsteps of the LHC and uncover yet inaccessible
phenomena.
  To foster the discussion on this important topic among the young particle
physicist community, the Early-Career Researchers (ECR) panel of the European
Committee for Future Colliders (ECFA) has organized the Future Colliders for
Early-Career Researchers workshop at CERN in September 2023. This document aims
to summarise this event and present the ECR perspective, outline the key
questions that came up during the discussions, and explore how ECRs can
influence the decision process of future colliders community and beyond.
