Positions count by year

Hover over a name to see the position and date range. This table only includes positions where at least the start date is known. The positions count can count the same person multiple times if they held different positions; similarly, the list of staff may include the same person multiple times if they held more than one position during a single year. For each year, a person is included if they were at the organization for any part of the year; this means the actual staff count at any point during the year can be lower (or higher, if some staff held multiple positions in a single year).

Roundtable: how can remote employees maintain a healthy work-life balance? 2019-10-26 Cash Callaghan Animal Charity Evaluators The Humane League, Centre for Effective Altruism, Animal Equality, Rethink Charity, Animal Charity Evaluators, ProVeg International Stephanie Frankle, Julia Wise, Antonia Vitale, Baxter Bullock, Leah Edgerton General discussion of organizational practices AI safety|Animal welfare The blog post is a roundtable between people working in executive, operational, and community health roles at organizations in the animal welfare and effective altruism spaces. It is mainly focused on how organizations with remote employees can maintain a healthy work-life balance. Some of the organizations are completely remote (they have no central office) whereas others have both on-site and remote employees. Common themes emphasized by multiple participants include: work-life separation through time (keeping clear working hours boundaries) and space (e.g., having a designated space for working in one's home), open and proactive communication, encouraging time off with leadership setting an example, and keeping a healthy level of social interaction through tools such as Slack.

It is mainly focused on how organizations with remote employees can effectively hire and onboard new employees. Some of the organizations are completely remote (they have no central office) whereas others have both on-site and remote employees. Common themes emphasized by multiple participants include: using "culture add" and not just culture fit (to reduce risk of homogeneity), frequent check-ins, in-person meetings where feasible, and culture orientation for new employees (either an explicit orientation session, or through Slack and check-in meetings).
