Today's my company's official final day with Slack.

Starting tomorrow it's nothing but the "superior" Google Chat. I will have no choice but to join the others who have already migrated over.

It also mean I won't have any access to messaging outside the office because I don't want to accept the security certs on my phone.

At least you don't have access to messaging on your free time.

@electrineer It was nice to have an option. With at least with Slack I always leveraged DND. So I never had an issue getting bugged after hours.

Its more about having contact into my team without giving my company full access to a phone they don't pay for if I want to use Chat.

But in general you are correct. No messaging means a guarantee that I won't be bugged now.
