“…The acknowledgement of such drawbacks has spurred some attempts to capture class trajectories as a whole sequence of events, rather than emphasizing some features of work-life mobility (such as the duration of posts held). SA -originally introduced from biology by Andrew Abbott -has been suggested not only as a means of finding resemblance in work careers in general (e.g., Abbott and Hrycak 1990, Araujo 2018, Blair-Loy 1999, Bühlmann 2008, Pollock, Antcliff and Ralphs 2002, Stovel, Savage and Bearman 1996 but also as an alternative to class mobility in particular (Bison 2011, Bukodi et al 2016, Bühlmann 2010, Chan 1995, Halpin and Chan 1998. As described in more detail in chapter 6, SA finds resemblance between pair-wise sequences of events by accounting for whether states occur of the same duration, in the same order and at the same time in the sequence.…”
