Pros
Most people love Wikipedia, and the movement is amazing. Being part of that is special. Pay is pretty good for a non-profit. Since it was largely remote already and hasn't yet lost revenue, its been a safe haven during COVID, and handled the current crisis relatively effectively. Many talented, interesting and inspiring people.
Kontras
As expressed in many reviews here, the leadership culture and specifically the c-team, their incentives and thinking, are really prime examples of American corporate leadership culture gone wrong. Little to no accountability, deep distrust, inability to hear "no", self-serving and personally ambitious, disrespectful of the values of staff and movement, focused on corporatizing and growing their control over participating as respectful partners to staff and volunteers. Years of negative staff surveys, particularly around leadership vision and accountability are basically shrugged off. The situation is particularly bad for middle and upper managers or people with significant experience. It can be a good place to work, but do not expect effective, thoughtful, values driven leadership. And do not trust the responses from HR or whoever that it is being "fixed". Thats been the song and dance for 5+ years of ups and downs. The incentives are not there for the leadership to change their behavior or way of thinking. HR can only do so much, and they too report to 2 c-levels who are part of the problem. So it is likely to remain this way, though more ups and downs, leaders coming and going, until economic circumstances or governance reforms force a change.
