Pros

Great office, barista, great benefits and perks. If it wasnt for my stocks I would have left by now.

Cons

HR is political. They have no idea what they are doing and not helping employees at all. IT department is political. They each bring people from their previous companies, and leaving tenured employees out to dry. Young, unexperienced, 2 years in IT kids are getting promoted to managers simply because they are good at sucking up and throwing people under the bus. You can work day in and night, if you didnt know your manager from another company, or if you are really giving them honest feedback you will get bad performance ratings and they will not promote you on purpose. People that were previously interns are now managing a team of 5 with less than 2 years on the jobs when Master degree, 15 years of experience professionals are just analyst. This is a joke. Upper management is amazing and is trying to promote a culture that no-one on the lower management follows because they count everything you say against you.

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

The level of talent and skill of the individual contributors on the recruiting team are some of the best in the industry. Leadership has also invested in elevating the talent through industry trainings with internal and external partners, which continues to uplift the already awesome talent on the team. Teammates genuinely care about each other and really empower each other to help one another through their work and projects together. Slack is and will continue to be an amazing product and I only hope that more and more organizations adopt the way that Slack is used at Slack.

Cons

No accountability from leadership (Directors and above) on the decisions they made that impacted the ability of the team to deliver and have enough resources to perform. There was a ton of organizational change and thrash in the last one year, not to mention everything going on with the pandemic/social justice issues/the election/etc. and, while senior leadership made statements about how folks would be supported through all of that and to take the time they needed, it was all just empty platitudes. Many decisions were made by senior leadership that impacted how the team was able to perform and deliver on targets, and the workload only increased even more while the team had been under-resourced for a long time. There was an increase in recruiting pipelines, increased number of required trainings, and increased number of required projects. After all of that, there was barely any value or recognition represented in the very small compensation increases across the team (or none at all) compared to previous years, and no equity refreshers for anyone in this organization. There was a severe lack of visibility from senior leadership and the previous culture of empathy and empowerment is no longer felt. Many people on the team have shared feedback with leadership about creating shared accountability and trainings with hiring partners but it ended up no where. Hiring partners will continue to point fingers at recruiting for not delivering even if they are a big reason why targets are not met. Executive partners don't see the value in recruiting and that was made very apparent in many ways. Team morale has been down for a long time (more than a year) and nothing meaningful was done to address it - leadership would just dodge feedback and/or questions from the team or spin the narrative around team feedback and morale. So disappointing because this was not the culture of the team for a long time and things had really changed in recent years. There's also no growth opportunities beyond a certain level. The outlined career paths for each level on recruiting changed drastically in 2020 and negatively impacted many people, leaving them with no opportunities to grow into higher level roles. Many changes were made to how each level was outlined and what was expected for each level, with a severe lack of clarity or visibility into those decisions. Now is not a good time to join the recruiting team at Slack. They're losing a ton of tenured and very skilled recruiting members on a weekly basis and they're just trying to fill holes and put bandaids on very big open wounds.
