Pros

I've been with Slack over a month and it's clear this company is led by an extraordinary CEO! A CEO who cares as much about people as he does the bottom line. His thought process trickles down throughout the leadership team and managers making Slack truly a wonderful place to work! Slack the product is an amazing product! While I used Slack at my previous employer, it wasn't near to the extent I'm now getting to use it. It's a product that truly makes work life simpler, while also adding in fun with all the emoji uses! Slack benefits are phenomenal! They have 3 health options in CA and that are 100% paid for by Slack for the employee AND the employee's dependents. This is a HUGE annual savings. They offer 20 paid vacation days, 10 paid sick days, 2 paid volunteer days, paid Company Shut Down days between Christmas and New Years and paid Holidays. They offer a cell phone and wellness stipend which are automatically added into your paychecks. Plus up to $1000 reimbursement to set up a home office and up to $2000 reimbursement for professional growth! Slack's pay is generous! They offer generous base salaries, annual bonuses and stock! A portion of your stock starts vesting at 12 months! Career opportunities also seem to be abundant at Slack. While Slack has over 2300+ remote employees (currently due to COVID), they have really mastered the "remote" workforce culture by having employees feel engaged without micro-management. I've feel blessed to have landed at Slack!

Cons

I have not come across a single "con".

Pros

Passionate and motivated employees that all believe the impact that Slack can have on its clients. The most progressive benefits I've seen - overall, and in regards to adjusting to the current environment. Great transparency from leadership and across the company. Once our customers understand the business value Slack can provide, they LOVE us, which is very rewarding.

Cons

Being a young company that has grown so fast, still developing more process efficiencies. Lots of constant change that can be challenging. Still defining more structured career paths, but huge push for personal and professional development of its employees.

Pros

Super smart and the kindest of humans to work alongside make my working life so pleasant. Slack works the way you would expect a company to work in 2020, fast, productive, value driven, passionate and undeniable belief in the product.

Cons

Slack is growing super fast and work output is high. This level of scaling in a distributed work environment might not be for everyone.
