Signing Ninjas and SFTs have emails.
at my store, the SFT is a TL
He wouldn't have made it as a TL but he was an amazing SFT.
So what is the point of changing the core role of the job?
To maximize the use of available payroll by globalizing team members and diversifying their workload beyond what was traditionally in their work center.
SFT's acting as Team Leads.
Salesfloor TM's instead of hardlines/softlines TM's.
AP TM's who spend 10% of their time doing store tasks instead of 100% of their time doing AP tasks.
I could go on, but you get the point. SFT's certainly aren't immune to the expanded core roles/global model that Target has been changing to over the years.
