Store automation and work design5 min read

Following changed work to the people doing it

Retail automation cases count the till hours they remove and rarely follow the work that remains. A board should approve self-checkout only after seeing where that work goes, who will do it and what it will cost in loading, advice and shrink.

    Collective bargaining5 min read

    Show the union your labour-cost model before the first offer

    Employers usually bargain by revealing as little as possible about their costs. When inflation has outrun a wage scale, I think the better course is to share the cost model with the bargaining committee early, within clear limits, and to accept the loss of a tactical advantage.

    Language at work in Quebec5 min read

    Stop asking Quebec managers for English the job does not use

    Many companies run from English-speaking head offices still list English as a requirement for Quebec management roles out of habit. I think every such requirement should carry a written reason, and that the cost of operating in two languages belongs at head office rather than in Quebec careers.

A leadership conviction

A people plan in retail is finished only when I can say who will do each piece of work it moves, at what hour, in which language and for what pay. Most plans stop at the hours they remove. Ours are tested in the yard, at the feed counter and in the small-town store where one absence rearranges the whole week.

I test every staffing, pay or technology decision by following the work it displaces to the person, the town and the language in which it will actually be done.

I am executive vice-president and chief human resources officer of Grangemont Farm & Home Inc., a retailer listed on the Toronto Stock Exchange that sells feed, fencing, pet, garden and hardware supplies through 168 stores in Ontario, Quebec, New Brunswick and Nova Scotia, with two distribution centres and a feed mill. About 9,600 people work for us year-round and roughly 11,200 at the spring peak, and about 2,300 of them are covered by six collective agreements. I am responsible for labour relations, reward, talent, HR operations and our French-language obligations, with C$352 million of annual compensation and benefits expense. I report to our chief executive, Martine Ouellard, and work from our head office in Guelph and our regional office in Drummondville.

I started in June 1996 as a night-shift supervisor in a grocery wholesaler's warehouse in Laval, with thirty-eight order-pickers and a union steward who knew the collective agreement better than I did. I spent the next seventeen years in unionised distribution and food manufacturing, as a labour-relations adviser and then running HR for a chilled-food plant in Saint-Hyacinthe and later for four plants in Quebec and Ontario. I moved into retail in 2014 at a housewares chain owned by a private-equity fund, and joined Grangemont in 2019, a year after it bought a 31-store Quebec chain and inherited its union certifications.

The questions I work on are practical ones. What happens to the work when a store installs self-checkout and a customer still needs a twenty-kilogram bag of layer feed carried to the truck? How should a company bargain when inflation has outrun the wage scale and a strike in April would leave its Quebec stores without seed? Who will run a store in a town of six thousand people when its manager retires? And why should a capable store manager in Victoriaville need English to be promoted? My answers have cost money, and in one case a saving I had promised and did not deliver.

Self-checkout without a layoff

In 46 larger stores we installed self-checkout and moved 117 cashiers into yard-loading and counter-advice roles rather than cutting their hours. Complaints about loading waits fell 44%. The net labour saving was C$1.8 million a year, not the C$4.3 million in the business case.

A five-year agreement without a stoppage

In 2023 we showed the union's bargaining committee our distribution-centre cost model before our first offer. The Drummondville agreements were ratified by 81% and 77% of members, and turnover in the distribution centre fell from 34% to 18% by 2025.

Store managers from the next town

A network of 34 hub stores, each carrying a second assistant manager in development, raised internal appointments to store manager from 31% in 2021 to 77% in 2025 and cut the average time to fill a vacancy from 143 days to 49.

French first in Quebec

We re-authored 130 training modules in French and removed English requirements from 12 of 14 Quebec management posts. Internal promotions to store manager in Quebec rose from 3 of 11 appointments in 2021 to 12 of 14 in 2024.

Current focus

I am rebuilding our store pay structure for 2027. Ontario adjusts its general minimum wage each October and Quebec sets its rate each May, and successive increases have narrowed the gap between a new seasonal hire and a department lead with eight years' service from C$2.75 an hour in 2021 to C$0.90 today. I am also preparing for the 2027 renewal of the two Drummondville agreements and checking whether the self-checkout lanes we redesigned this summer have brought shrink back to its earlier level.

Conversations I welcome

I am not seeking another executive role. With Martine Ouellard's agreement and our board's approval, I would consider one non-executive seat, ideally on a human resources and compensation committee, at an organisation that neither sells to farm, pet or hardware customers in eastern Canada nor supplies Grangemont. I accept a small number of advisory and speaking conversations each year, in French or English.

Sebastian brought the committee the page on what a strike would cost before anyone asked for it, and later asked us to cut an incentive measure that would have flattered his own programme. Directors learn to rely on an executive who does both.
