Hospitality treats departures as weather — unavoidable, unbudgeted, absorbed. So nobody costs them. But a departure is a purchase like any other: you're buying a replacement, and the invoice arrives in pieces over two months. Put numbers on the pieces once and staff retention stops being an HR virtue and becomes a line item.
The invoice, piece by piece
- Recruiting — writing, posting, sorting, interviewing: 15–20 manager hours at 35/hour is 525–700 before anyone is hired
- Training overlap — two people sharing one station across the first weeks: 40 hours of genuine doubling at 28 is another 1,120, paid to produce at half speed
- The slow ramp — a new bartender pours looser and slower for the first weeks; on a bar doing 2,000 a week in drinks, even a few points of over-pour and remakes is 60–80 a week until the habits set
- The knowledge that leaves — specs, supplier quirks, regulars' names: the part no line above captures
Add it up and an ordinary hourly departure lands between 2,000 and 3,500 — a number most operators would challenge line by line until they compute their own. That's the honest way to read industry claims about turnover costs, too: don't trust a universal figure, run your own wages through the same arithmetic.
The ceiling case
The range above is for a departure that only costs you *time*. When someone walks out carrying knowledge that exists nowhere else — the specs, the batch sheets, the why behind every pour — the invoice changes scale. I've written up what losing a head bartender actually cost; the short version is that the wage was the cheapest part. The difference between the 2,500 departure and the 50,000 one is whether the knowledge lived in a person or in a system.
Shrinking the invoice
You can't budget departures away — hospitality churns, that's the trade. What you can do is attack the expensive lines: documented specs cut the training overlap (the new hire learns from the fiche, not folklore); a certification path compresses the slow ramp; and writing the specs down converts the catastrophic departure into an ordinary one. At Chat Noir every recipe is documented and costed — when someone leaves, the recipes stay. Retention is the cheapest line of your whole labor cost, and training the replacement starts from the team guide, not from zero.
