Pros

Great, fun product that is beloved by customers Amazing talent on the ground. So many great minds. "Mature" startup with great perks Work/life balance

Cons

Lots of confusion, fake empowerment, meanness and secrecy. Competition within the marketing team, project stealing and disrespect of people's roles. Constant undermining to the point where even senior managers are informally demoted and cast aside. Overt favoritism, earned by being a yes man or woman and doing what you're told. The favorites can do ANYTHING they want, while others can do nothing right. Zero support from leadership. Inept, threatened, aggressive leadership with major imposter syndrome. There's nothing to learn from those in charge. In fact, be prepared to teach and then be punished for being "outspoken." Short-term thinking and planning resulting in missed opportunities. Hiring too many too fast, with overlapping responsibilities. Roles aren't defined well so it's hard to know who does what. Excited new hires are allowed to run with projects without including the right people. Before you know it, you've become redundant. HR has no power to help, as people are regularly complaining and inevitably leaving or being pushed out.

Thank you so much for sharing your thoughts with us. Although it’s disappointing to hear this has been your experience at Slack, we appreciate your candor and your perspective. We take all employee feedback seriously. Slack is a growing, dynamic organization focused on creating a great working environment with trust at its foundation. We encourage employees to meet one on one with their managers or People Partners to share feedback regularly. This type of assessment is incredibly valuable to us as we scale and we will work hard to improve. Thank you.

Pros

- Intelligent, kind, fun, caring coworkers - Personal/Professional Development Budget for each employee - We take our values to heart and that comes from the top down - The work/life balance is great (work hard and go home) - There is constant discussion among all employees about how we 'do that right thing'. That looks different for everyone, but I appreciate that there is always an open dialogue around the decisions we make across the whole company - Experience managers/leadership. This isn't their first rodeo. - Diversity matters here and is openly discussed - I am able to focus on my work and I know that Slack will do right by me (comp, benefits, culture, work/life balance, etc.) - I could go on and on...

Cons

- If Stewart told me to jump off a cliff, I'd probably do it. - I'd OF COURSE rather be overly PC then not at all...but it can be a bit much sometimes.
