I wouldn’t treat the staff so cruelly.
Rota should be a bit more consistent and posted maximum Thursday afternoon, slightly bigger orders on some cocktail ingredients, raise the bar on the cleanliness of the bar.
Morale boosts, team building, frequent team meetings, more local incentives for individual restaurants.
Rota to be completed earlier instead of being published Sunday afternoon.
Offer job shares and training programmes to people who can only work part time, have rotas completed 1 month in advance, do regular appraisals and staff meetings
