Insider ex-employee view:
Waitrose like ways to incentivise people, but only moderately.
There’s something called “Pay for Performance” which (allegedly) means staff hourly rate of pay is linked to performance.
(management speak for persuading all staff to commit to training in their spare time in the move towards zero hour contracts).
The thing is, the margins between SUPER DUPER TEAM PLAYER and GLUM STAND AT TILL AND GRUNT pay were so small they didn’t actually make any difference in motivating people.
Junior manager jobs and supervisor jobs in retail are still notoriously hard to fill as most normal people see it’s only a few pence an hour more for lots of extra effort.
So it’s all psychological money power play at Waitrose, but at a fairly moderate level.
