I have been working at SLACK Incorporated full-time (More than a year)
High quality products and content. Well-respected in its industry. Wins lots of awards. Doing very well revenue-wise in an industry that mostly isn't. Excellent group of people. Almost everyone is very good at what they do without being "aggro" about it. Corporate culture is centered around treating everyone equally. Still owned by the family that founded it.
They tend to pay below market value. This means that there is a much higher rate of turnover than there should be for a company doing as well as they are. This has gotten better since the start of 2015, when some of the "factory culture" policies were eliminated. Upper management tends to micromanage more than they should.
Advice to Management
You get what you pay for. Reward your best performers with larger raises and bonuses. Keep up with the professional development initiatives launched recently. Upper management needn't micromanage middle management unless they're underperforming. Continue evolving toward "knowledge worker" culture instead of "factory worker" culture.
