Picking a profile picture, choosing which biographic information to fill out, which pictures to share and even how we interact (likes, comments, messages), and with whom: these are all examples of how self-presentation may enter our considerations when we use social media. These dynamics and considerations are well described when discussing the mixed audiences of public-facing social media (van Dijck, 2013; Scolere et al., 2018). What exactly the relationship between social media and working life is supposed to be has been a source of controversy for some time (Bagger, 2021). In this chapter I will discuss how this is no less true when social media migrates clearly into the workplace in the form of enterprise social media (ESM) (Leonardi et al., 2013). I discuss this both via the existing research, and by providing three examples of how workers choose to tackle self-representation on ESM.
