It's not the company it used to be

Pros

- Great salary & benefits - Beautiful offices - They hire talented people - Cool & likeable product

Cons

Between 2017 and mid 2020 I absolutely loved working for Slack. The work was enjoyable, the offices were great and the local teams are really good people. The opportunities for growth were very limited; I was only ever promoted once and I had to really push for it. The reasons for not being promoted were completely out of my control (e.g. the company isn't growing fast enough). I worked above my pay grade and did managerial level work for no recognition or development opportunities. Management, on the other hand, were promoted annually. Even to the point of the most recent promo cycle this month, many promotions in BizOps went to Managers who are now Sr Managers / Directors. Everyone 'beneath' this rarely gets a look in. I always commended Slack leadership for being very open and transparent. Due to the upcoming Salesforce acquisition, the company has become incredibly secretive. The employee acquisition FAQ stated that there will be *no* redundancies -- however, there have been countless people being pushed out, including several people on my own team. But Slack doesn't communicate this, it seems everyone is keeping quiet to avoid ruffling feathers. In the end, I left before I was pushed out, which was a real shame, as I loved my time at Slack for the most part. If you're in PDE or Sales, Slack will look after you. Everyone else is at risk.

Pros

I've worked so many places where the product makes every position within the company feel like hell. Slack's product makes working there so easy and the culture and benefits around it make it even better. Work/life balance is the best I've ever had and I'm hoping this stays similar post acquisition. My teammates and those I work with cross-functionally are some of the smartest people I've ever met. Compensation also feels competitive across the board from what I've seen and the benefits, perks, and bonus opportunities are also great.

Cons

So far so good! I have given feedback on some of my experiences, but I feel as though it is actually heard and I wouldn't call any of these cons to working here. Come join us!

It's getting more corporate and less diverse

Pros

We're maturing as an organization

Cons

Prominent black leaders and other URM employees have left the company. We can live to see better days but we can't lose our company culture and values.
