Pros

This has been a a review I've been debating to write for a very long time. Slack is great for so many reasons. There are wonderful people here and people that really challenge you to be the best you can be. It is a place where you can be scrappy and explore your role. It is a place where you could feel very valued. It is a place that is very appealing b/c of how well the business overall is doing.

Cons

Now for the bad. I can't even keep track of the number of bad days I've had at Slack. This review is not for the company at a whole, but for a specific department. You are extremely over worked and under appreciated. You get threatened that you'll get fired or put on a pip, you never know when you need to tip toe around something or if you should be assertive and make decisions. You get blamed for every mistake, and are criticized for not being the most cheerful and positive person on the planet. You get yelled at and you will cry. You will share your feelings with your colleagues, and they will stab you in the back. You will try to open up, and see that those messages have been shared with someone else. All in all, this is a stressful, emotional and political place to be. A lot of changes have been made recently, and maybe there is hope at the end of the tunnel.

Pros

An elegant, disruptive product with a compelling mission and strong delivery. Very smart, motivated, and passionate employee base.

Cons

I feel like I'm watching Death of a SaaS salesman play out right before my eyes. We have an amazing product, an amazing opportunity...lots of pipeline...yet it's nearly impossible to make real money. Why? Because commission rates are at the absolute bottom of the market. If you've been accustomed to a typical SaaS commission rate of 10%...you will NOT find that here...not even close. At Slack, your commission rate will be at 3% or less. Yes, it's true... if you close a $1M deal, you will only get paid about $30K before taxes. It's unclear whether this is a CEO driven philosophical shift in not rewarding the revenue generators of the company or whether it's because Slack sales mgmt has come from non-enterprise sales roles at companies or channels where they have historically underpaid sales people (ie. DropBox, SFDC Commercial/SMB, LinkedIn etc)... but it's become a shock that has rippled through our sales org at the cost productivity. It's demoralizing, distracting, and disappointing, especially for the newer sales hires who were misled to believe they'd be able to make real money.
