Ask HN: How do you react to a promotion?

I got a promotion after a long time. (Based on the performance, I should have got long ago. But I never asked for it. And the usual office politics, favoritism didn't help either). Hardly any difference in terms of compensation. (Just a low single digit hike.) Two questions.

1. I saw it in workday portal. My manager is yet to have a meeting with me to inform. How should I react when he informs?. I appreciate the fact that they finally acknowledged my efforts. They have very limited budget. But if I sound happy, they may take me for granted again. ( Please note, it was because of skip level manager that I got this promo. I don't think my direct manager had any influence)

2. I was fed up with the overall environment and was planning to do the minimum required work.( Difficult to implement though, since I was always passionate). But now that I got the promotion, the expectation will be high. Hence it will be difficult. So I am confused with this promotion.

Have you been in this position?. How did you handle ?
