claw back = 元に戻す、復旧、返還、

But nimble firms have other options: the employment version of shaving bit of chocolate from the bar. Some cut costs by boosting output per worker, often by driving workers harder. Tellingly, growth in output per worker now tends to fall in booms and rise during busts, precisely the opposite of the pattern 40 years ago, when inflation was high. Firms can respond to market pressure by reducing the benefits available to workers; Asda, a supermarket, recently announced plans to slash British workers’ holiday allowances. Or they can offer workers more tortuous schedules. Research published in 2017 suggests that being able to vary workers’ hours from week to week is worth at least 20% of their wages. On the flipside, during good times firms often opt to reward workers with office perks and one-off bonuses, rather than pay rises that cannot easily be clawed back during downturns.
