And you can see how the cycle is going. A low wage worker quits and gets a better job. And the first job had a vacancy and the only way they can survive is to pay more. So wage growth goes up. And both jobs have low productivity workers because they are new and this is stagflation pretty much.
if a restaurant made good food in the first place it would self sustain
restaurants that make poor cheap bland food natural see customer shrinkage thus then see income shrinkage that then see lay-offs and eventually close due to unsustainability
as for staffing
hiring people in 2019, training them up adding in costs of pensions and other employment benefits puts some employees way above min wage in 2021.. when a business needs to go back to bare bones lowering outgoings and increase income.. they need to kill off the dead wood. first they need to remove the main large cost employees and swap for cheap labour. not the opposite
the only time the opposite is true is when they want to rejuvenate, renovate, rebrand or re-open under new management as a offering good food again to grab more customers again
this requires a large investment and training and benefits
in more cases than not.. businesses opt for the first option. to decrease outgoings
most of the time you cant just legally lay-off someone for bland reason. without offering a severance/compensation. so easiest way to get rid of dead wood and do it cheap, annoy the heck out of them until they leave out of their own free will
(stop offering overtime, promotions, flexitime. change their shift schedules. ask them to do work favours during breaks)
