Funnily enough I was hired on a 12 month contract as a software developer.
Four months into that contract I was moved over to a struggling 'Slack' enabled project, to help them work through their ever growing backlog.
I knew someone working on that project and discussed with them the project's use of Slack only to realise it was nothing more than a talk fest and not for me.
So when the project manager approached me, asking if I would like to join in on the Slack discussions, I declined.
Needless to say that did no go down so well.
However, I stuck to my guns and 12 months on my contract was renewed.
To this day Slack is still not part of my daily development life.
