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.
