Pros

- Slack is an amazing company that cares for people and customers. - CEO, CTO and all other executives are awesome. They always take care of the employees. Especially during COVID19 crisis, all executives showed a great character, allowed employees to settle down and adjust to the new situation and made sure work-life balance is maintained even when people are always staying at home. - Some perks offered during COVID19 crisis : Flexible working hours, $1000 stipend to buy WFH equipments, special time off for emergencies and permanent (optional) remote work.

Cons

Stiff competition from Microsoft Teams.
