clock off

休日に思いっきりリラックス出来ない方は、以下のことが原因かもしれません。

Can’t help checking emails late on a Saturday night? That could be a personality problem – but there are ways to keep these habits in check.

They clock off at 9pm on a Friday – but their last email is logged at 3am. They take conference calls on holiday, wake up in cold sweats over looming deadlines – even their sleep talk is peppered with business jargon. By Monday morning, they look like they’ve spent the whole weekend hunched over their laptop, wired on coffee. It’s hard to believe they ever left the office.
Why is it that some people just can’t relax at the weekend?

Across the globe, a heady mix of individual ambitions, brutal organisational cultures and the technology to make work accessible 24 hours a day is contributing to a spiralling crisis of stress. The American Institute of Stress estimates job stress costs the US economy about $300 billion in lost productivity every year. According to research by online travel company Expedia, just 53% of workers come back feeling rested after they’ve been on holiday.

記事の中で気になった表現は、"clock off"です。

LDOCEで調べてみると、"to leave work at the end of the day"や"to record on a special card the time you stop or leave work"とあり、『ジーニアス英和辞典』第4版(大修館)で確認すると、"clock out [off]"で「(タイムレコーダーで)退出時刻を記録する」「仕事を終える、(仕事が)終わる」とありました。

ここでは、「仕事が終わる」という意味で使われています。(Akim)
