For the rank-and-file TM, those standard operating procedures are not readily accessible. You need TL or ETL access rights. You are expected to simply perform your job as you are directed by the TL or ETL on duty that day, and hope like hell that the TL or ETL on duty on another day doesn't get pis**d that you failed to follow correct procedures.
This is where the Store Modernization buzzwords of "empowerment", "ownership", and so forth conflict with real-life reality working in the stores as well as the DCs. Most businesses need to retain at least some staff members who have longer-term experience than new hires. Retaining experienced TMs is not simply for the purpose of training, assisting and role modeling for new TMs. It's also to diagnose and resolve unexpected problems which arise intermittently and sometimes at the worst possible time, which newly-hired TMs or straight-from-university ETLs might be unable to efficiently diagnose and solve.
It's not clear to me what Corporate's purpose is in their approach to pay for hourly TMs, other than to push out the door experienced TMs and focus exclusively on new hires who might actually be very capable and competent but nonetheless lack experience handling things like malfunctioning Zebras and broken cash registers and PIN pads.
