That line of thinking makes no sense to me.
Currently it seems this business loses an employee every month other than the standard "going away to college" during the summer months.
You have an employee who shows up at work when they are supposed to, they do what you tell them to do, and they work longer then they are scheduled for, it makes no sense if that employee who has the second longest tenure at the business doesn't make what everyone else is making in a heartbeat vs the PITA factor it will involve in finding a new employee that will be just as good and dependable.
It's actually kind of an insult to hire people with the same amount of experience at a higher pay rate IMO.
I really hope my kid does find another job LOL
That said, kid is smart IMO. Kid deals with it because already has saved over 5k in the 7 months there, and has only been applying at one place at a time to given the potential new company time to get back so multiple offers don't come in at the same time, and looking at higher end places in hopes to be a server before high school graduation. I've mentioned the best gig I had in college was waiting tables at higher end places because the ticket prices and the tips add up. As I explained, would you rather make 15% on a $30 meal for 4 or 15% on a $90 meal for 4?
