Pros

Slack accommodates personal, family, physical and mental health needs during the COVID pandemic through emergency time off, mental health programs and work schedule flexibility. Through this time where offices are closed and everyone is remote, team leads also make extra effort to keep their organizations connected socially, whether it is through Halloween luncheons or weekly banter message threads to find out how everyone is doing. Performance is measured based on Objective-Key Results which are thoroughly fleshed out quarterly or semi-annually through manager feedback and support, providing employees clarity and concise feedback needed to do their jobs well and advance their careers. Career development options are also top notch, with a generous allowance for employees to embark on professional development courses and opportunities to bungie into other departments temporarily to allow us to discover their passions.

Cons

Too much transparency when it comes to executive ask-me-anythings. Such a culture may distract employees from their primary roles and overall company goals/objectives. This provides room for dissent and surface-level policy criticisms that do not fall in line with the overall company's direction. On the other hand there is a relative lack of transparency in the remote work application process compared to how industry peers have made available information on the revised pay scales per remote location. Such information is furnished only when an intent is indicated through a remote work application, and for the specific city an employee intends to move. Paybands are set based on overall state (except the Bay Area), so for example the payband for Bakersfield CA or Redding CA is the same as for Los Angeles. However overall Slack is bias-to-yes for most remote work applications, and provides said information on a timely basis. More funds could be disbursed to support compulsory and voluntary work from home arrangements and setups given the COVID pandemic is set to last a long time. The current amount of $1000 could be revised upwards to account for more permanent ergonomic arrangements and office-quality equipment. Nonetheless $1000 is a significant amount that indicates the company's support for its remote working employees to have a good home office setup.

Pros

Leadership, work-life balance, culture, community

Cons

Everything you would expect working for a hyper-growth, recently-public company. Lots changing at all times both internally and externally but I have total trust in our team to bring us through any/ everything, which says a lot.

Considerate corporate culture with good work-life balance

Pros

- Slack is the most considerate place I've ever worked. That come through both in small ways (colleagues are really thoughtful about each other's time, people are welcoming) and big ones (company-wide, there's an expectation that management will preserve and model good work-life balance). - People care about making something that's helpful and pleasant to use, as well as successful. It's such a great outlook that makes it fun to be part of building Slack. - Benefits and comp are competitive with similar companies. - Slack is a big enough company that there's a lot going on, but not so big that it's hard to feel at home or see where your work fits into the bigger picture.

Cons

- The downside of Slack being so considerate is that sometimes the company culture isn't direct enough: It can be tough to know who owns a decision, and often people are so gentle with their feedback that it's not actually useful. - Prioritization isn't as good here as at other tech companies I've worked at. We often have more "priorities" than the teams we have can feasibly work on. - Leadership isn't as transparent as they seem to think they are (and, to their credit, as I think they genuinely want to be). Internal comms are not a strong suit.

Thank you for your thoughtful review. It’s great to hear that you feel at home at Slack and surrounded by supportive colleagues and culture. Transparency from leadership is very important to us and we encourage you to share your concerns in our executive “ask me anything” channel, in our regular pulse surveys, or directly to our people partners and/or your manager. Thanks again!
