Pros

Pay, culture, work-life balance, psychological safety.

Cons

There's not many at all. But internal business changes can be annoying at the moment. Still cannot fault many things!

Pros

Love the majority of slack employees I work with

Cons

Salesforce feels like a cult with animated characters and a huge love for appropriating Hawaiian culture (and Salesforce owns slack and forces their culture on Slack)
