My only question is what are employees proposing CoinBase takes a stance over? If you want something like cryptocurrencies to thrive you can't be overly policing them, that's not your job as a company.
Your job is not a political platform unless you work with politicians on their campaigns or are a politician / other form of politically affiliated / influenced company.
Politics can make people feel extremely uncomfortable especially if they feel suppressed and as a minority are bullied by other employees.
I made another longer comment about it on this thread.
The gist of it is that a competent HR department can make a statement without directly committing support to any particular organization or group that they aren’t comfortable with.
Saying “I refuse to comment and you’re not allowed to comment” is the worst way to go about it, literally anything would be better.
There are also ways to train on empathy, bias, and general employee-to-employee communication that can guide employees through those conversations with colleagues.
Regarding bias training that you mentioned, the Heterodox Academy did a literature review and concluded that there isn't adequate evidence to conclude efficacy and if anything the effects are deleterious on workplace cohesion.
It seems much more time-deaf to think that everyone wants to be involved in this highly stressful, chaotic game of identity politics. Some people just want to do their job. Personally, I want to focus on what I'm working on while at work, not have my boss preach their particular views at me. I bet the meetings/memos were not very tone-dead if you were there to work on what the company was doing.
My guess: 1-2% of those people are the loud, annoying group that demands everyone behave how they think they should, and the other 3-4% were people who saw an opportunity for a long paid vacation while they look for another role.
I bet they didn’t have 5% turnover over some time-deaf email from the CEO.
My guess: those 5% got sick of tone-dead all hands meetings/memos and saw their chance to bail out.
I wonder what other companies during the Covid recession has 5% voluntary turnover?
