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.

Pros

Slack is a great product with a lot potential. Great customer base and sales team. There are some really smart and kind people through the organization. Not a workaholic culture with staff leaning older the culture feels a lot more mature. No beer, foosball or frat boy antics. Great compensation and benefits. Interesting problems to solve. Stills feel like a startup but that will probably change soon as there are signs that big company culture is on the way.

Cons

Slack has a serious culture problem especially in the marketing organization that just grinds people down to a pulp and discards them. Marketing leadership has been allowed to drive the morale down of the marketing team. The marketing organization is a hot bed of opaque transparency, silencing tactics, favoritism, unannounced informal demotions, bullying tactics including just deciding to stop inviting key people to meetings, silent treatment and coverups, poor operational procedure, lack of vision, lack of insight into decision making with with no oversight from our CEO. The culture amp survey scores for the entire org are in material decline, and there is a consistent show of sloppy vision from the top that keeps marketing operations in a state of confusion with constantly blown scopes and massively off track projects, thrashing and things changing every other week. Attrition is bad people who don't get bullied out of the organization are starting to leave on their own accord. The People Org has watched all of this go on and it continues to happen with seemingly very few alarm bells being rung . The morale of the marketing organization is in serious decline and many key figures have gone missing with very little explanation. Leadership has been allowed to run amuck and people are too paralyzed by unchecked power and are too fearful to disagree because they know the consequences—their careers. There is no recourse for you if you are a victim of leaderships quick disposal of you. Everyone in the organization sees this pattern and it is an open secret. The marketing organization has been tasked with a lot of meaningful company goals and the insecure, inhumane, bullying tactics are going to be the make or break in the entire team’s success. There are very talented people on the team and talented people have been forced out if they pose a threat or challenge leadership. Making a mistake can ruin your career. At the top of the organization is leadership is only about itself and its career aspirations and it does not care about who it has to step on, ruin or use to get there as long it keeps favor in our CEO's eyes.

Pros

Game changing technology and massive market opportunity ahead - We're 1% penetrated in a 700 million knowledge worker market. Unique culture that emphasizes customer and team first. Great opportunity for career growth: A colleague was promoted to manager role and many others have been promoted into Senior AE roles. Achieved some great milestones in 2017 including landing Large Enterprise logos that few 4 year old companies can boast about: IBM, Oracle, SAP, American Express, Capital One, eBay, Paypal, Walmart. Best parts about working at Slack: Being surround by intelligent, empathetic teammates, helping effect a fundamental change in how people use technology to get work done, exciting personal career growth and earnings opportunities, and visionary leadership from Stewart Butterfield who has surrounded himself with an impressive executive team.

Cons

The sales organization still comprises a smaller percentage of the total employees, so developing a strong voice/seat at the table with larger product and engineering organization has taken time. I've seen positive changes over the last year here so I anticipate progress will continue to improve.
