。
She demanded a raise.
Literal
She [topic-は] pay-raise [object-を] demanded.
昇給 (しょうきゅう) combines 昇 ('rise') with 給 ('pay, salary') for 'pay raise.' 要求する (ようきゅうする, 'to demand, to request firmly') is stronger than 頼む ('to ask') — it implies assertive insistence. The sentence paints her as proactive about compensation.
