What 2,000 People in a Slack Channel Taught Us About Workplace EV Charging

Imagine a company with 2,000 employees and eight EV charging stalls. Not unusual. Early charging infrastructure often gets installed in small batches, before anyone expected this many EVs. The facilities team created a Slack channel: #ev-charging. The rules were simple: post when you're leaving, first response gets the spot. Seemed fair. First come, first served.

Six months in, the channel had become a source of low-grade workplace tension. HR had received three complaints. A few employees had stopped trying to charge at work at all. The original poster of the channel policy had quietly stopped using it too. What went wrong?

The Speed Trap

The Slack announcement model has a fatal structural flaw: it rewards whoever sees the message first and can respond immediately. On the surface, this sounds neutral. In practice, it's anything but.

Consider who wins at Slack notification speed: employees who work at a fixed desk all day with notifications on, employees who have few or no meetings, employees who are in the same time zone as the person posting, and employees whose workflows allow for frequent context switching. Now consider who loses: employees in back-to-back meetings, employees who work in focus modes or use Do Not Disturb, employees who work earlier or later shifts, remote employees who work on different schedules, and employees who are conscientious about Slack hygiene.

This isn't a hypothetical. In the 2,000-person company, analysis of the channel showed that 70% of stall claims were made by fewer than 15% of the EV-driving employees. It wasn't that those 15% were bad actors. They were just the ones who happened to be looking at Slack when the message hit. But to the other 85%, the pattern was indistinguishable from favoritism.

The 'First Come, First Served' Myth

First come, first served sounds like the most neutral system possible. But in a Slack context, it isn't first come, first served in a physical sense. It's first to respond to a digital notification. Those aren't the same thing, and the difference matters.

Physical first-come-first-served (like a line at the grocery store) has a clear, verifiable order. Everyone in line can see who arrived before them. There's no ambiguity, no information asymmetry. The person at the front got there first; everyone can confirm this.

Slack first-come-first-served is opaque. The 'line' is invisible. You don't know how many other people are waiting. You don't know whether you just missed a spot by 30 seconds or 30 minutes. You have no idea where you stand at any given moment. This opacity is corrosive to the sense of fairness, even when the underlying distribution of stalls is actually random.

What Resentment Actually Looks Like

The HR complaints in the 2,000-person company weren't dramatic. Nobody was accusing anyone of corruption. The complaints were vaguer but arguably more insidious: 'It feels like the same people always get the spots.' 'I never seem to be online when it posts.' 'I've given up even trying.'

That last one, giving up, is the real damage. It means the benefit stopped benefiting the people who gave up. They still drive EVs. They still need to charge. They've just concluded that the workplace system doesn't work for them and made other arrangements: charging at home the night before, looking for public chargers, paying out of pocket for the privilege they're technically supposed to have at work.

“The employees who give up quietly are often the ones with the least schedule flexibility, and the most legitimate need to charge at work.”

What Fairness Actually Means

Fairness in a shared resource system doesn't mean everyone gets the same access on any given day. It means the distribution of access over time is equitable, transparent, and not systematically biased against any group of employees.

A real queue (not a Slack-message queue, but a managed queue with a visible position, a known wait time, and an automatic notification) achieves this. You join the queue from wherever you are, regardless of whether you're in a meeting or on a call or working from another building. Your position is recorded. When your turn comes, you're notified. You either show up or you pass, and the next person gets a chance.

This model doesn't require the fastest fingers. It doesn't reward the most Slack-addicted employees. It treats the charging stall as shared infrastructure that everyone has equal standing to access, in a rotation that's visible and verifiable by anyone.

The 2,000-person company adopted a queue-based system after the third HR complaint. Within 30 days, the complaints stopped. Six months in, the group of heavy users had expanded from 15% of EV drivers to over 80%. That's not because there were suddenly more stalls. There weren't. It's because the stalls were finally being distributed fairly enough that most employees trusted the system enough to participate.
