Also in two minds, having worked in the civil service before. There was a slight panic when it became understood that unpaid Slack didn’t actually delete messages beyond the latest 10k; as soon as you started paying they’d all be available. Not that there was anything definitively problematic, but it just would take one newspaper to request “all Slack messages from the day before the brexit vote” and suddenly there’d be problems with the public’s perception of civil service political neutrality.

Because to be honest, everyone is political in some form or another, especially the people that effectively take a pay cut to work in the civil service because they want to help citizens, and it’s a daily challenge to keep that political nature from spilling out into your work.

Everyone needs a place to unburden, and if you’re legally forbidden from doing that with friends and family you rely on the workplace. In the end the best I could do was make a FOIA reaction emoji to remind people to tone it down if something could be perceived in the wrong way by the press.
