She forced the work onto me.
Literal
She [topic-は] that work [object-を] me [target-に] pushed-onto.
押し付ける ('push onto, force upon') is a compound verb fusing 押す ('push') + 付ける ('attach') — 'attach by pushing.' Used for any imposed burden: tasks, opinions, blame, even people. The structure [recipient]に + [thing imposed]を + 押し付ける. Carries an unambiguously negative tone — the recipient didn't want it. Compare with the formal 課する (institutional imposition); 押し付ける captures the personal, unfair flavor of being saddled with someone else's responsibility.
