Pros

Many teams at ICON foster a collaborative and respectful environment, with colleagues who genuinely care about delivering quality work.

Cons

Changes in structure or staffing often lacked clear communication, leaving teams uncertain about future priorities or stability. For those impacted by layoff, notification processes could feel impersonal — a missed opportunity to reinforce dignity and appreciation.
