Pay cashiers/front end staff better. Minimum wage might be an ok starting wage but staff deserve raises after a year of service, which they don't get, often not even after 2 or 3 years.
No favoritism, no nepotism, managers that create a team and not tear the team apart with favoritism which causes animosity. needs to be unionised. HR does NOTHING for the employees, especially long term HARD working loyal employees.
