The professionalization of transitional justice (TJ) has received extensive academic attention in TJ and related international relations and peacebuilding scholarship. This article adds an element that has received hardly any attention: namely the presence of activism even among professional and usually donor-funded TJ work. I argue that noticing activism in professional contexts requires attention to the ‘everyday’, meaning to life in between, aside and beyond high politics and officially important actors, actions, processes and events. Based on field research in Sierra Leone and Kenya, I describe and discuss everyday examples of a specific form of activism, namely tacit activism that I encountered with three key interlocutors, one Sierra Leonean and two Kenyan nationals involved in professional donor-funded TJ work. Their activism was ’tacit’ in the sense that it was not part of their official project activities and my interlocutors did not advertise their extra plans and efforts to (prospective) donors. And yet, it was precisely through these tacit plans and efforts that they hoped to meet at least some of the expectations that had been raised in the context of professional TJ projects.

过渡司法（TJ）的专业化已在TJ及其相关的国际关系和建设和平奖学金中得到了广泛的学术关注。本文增加了一个几乎没有引起注意的要素：即，即使在专业且通常由捐助者资助的TJ工作中也存在行动主义。我认为，在职业环境中注意到行动主义需要关注“日常”，这意味着除了高层政治以及官方重要的参与者，行动，过程和事件之外的生活。基于塞拉利昂和肯尼亚的实地研究，我描述并讨论了一种特定形式的激进主义的日常实例，即我与三名主要对话者（一名塞拉利昂人和两名肯尼亚国民，参与由专业捐助者资助的TJ工作）遇到的默契激进主义。他们的行动主义是“默示的”，因为这不是他们的正式项目活动的一部分，我的对话者也没有向（潜在的）捐助者宣传他们的额外计划和努力。然而，正是通过这些默认计划和努力，他们希望至少能够满足在专业TJ项目中提出的一些期望。
