〜っぱなし：~ keeps on happening; ~ stays as it is, to leave ~ as it is

昨日は仕事で朝から炎天下の中、外で一日中立ちっぱなしだったので、日焼けもしちゃったし、足もすごく疲れたので、帰ってベッドに直行だったんですよね

Yesterday, I was standing outside all day since morning in the scorching sun for work. As a result, I got sunburned and my feet became extremely tired, so when I got home, I went straight to bed.
