The article introduces the 'Sunset Clause' concept—setting a deadline to honestly evaluate whether an employment relationship should continue—as a tool for both employees and managers. For workers, it prevents being trapped in ambiguous roles by forcing clarity on career progression and organizational commitment. For managers, it provides a structured way to assess project success or departmental transitions. The key insight: regular communication is essential; the deadline is only meaningful if ongoing feedback conversations happen. Neglecting communication and then imposing a cutoff risks unfair performance judgments. The takeaway for Thai SMEs: use sunset clauses in employment arrangements and project timelines to drive clarity, accountability, and intentional career/organizational planning.
