At my job I created a slack bot that posts a daily random leetcode challenge every morning (easy and medium difficulty only, for now). It's there for fun because we're a team of devs who love coding. But I also created it so I can practice every day just in case I get laid off (we had 2 rounds of layoffs within a year).
But honestly, I'd still enjoy the daily challenge either way
Framed as team events, challenges, building exercises, etc. most companies will allow short frames for them. It's all in presenting superiors with a cost analyses that speaks to them in their native language: Profit/Loss/Excel.
