Top-tier

This app and the Company that I have been working for is excellent for communication and production for the fact that you can always go back view jobs and connect with everyone so easily

bro

I SPEND 10 MINUTES WRITING TO HIGHER UP IN THE COMPANY, THEN I TRY TO SEND IT AND IT GOES OUT OF THE PAGE AND DELETES ALL OF IT. like bro how hard is it to make a save feature all other apps have it. the thing is is that im forced to use this app by my job anyway so like genuinely what do I do.

Partnership Success Manager

I love using slack with my colleagues and to use it as a resource in case I need to find information about our products and services. The search tool is amazing as it looks into all channels. Thanks Slack!

Exactly what I’ve been looking for

you know how there's never a communication app that fits professional needs? RIGHT HERE. PERFECT. Heavily organized, with channels, DMs, groups, & threads. It saves message drafts across restarts. So many inbuilt tools, it could replace most of the Google Suite. And multiline messages support!!!

Not for me

Too much. Modern world needs simplicity. I think it should be illegal to have a leash like slack on people’s phones. Separate phone from work or provide me a work phone.
