Congrats... biggest thing I've learned in my transition... being an ETL is cake compared to being a TL. The hours suck, but I honestly don't do much more, I'm just "required" to be there longer.
That's my biggest gripe, I can accomplish everything I need to and then some, be ready to head out after a 10 hour day, but it's "frowned upon" by my peers. Instead of goofing around and grabbing starbucks, I tend to talk with TMs, do a pull, or take over a register for a cashier to do reshop; folks seem to dig it.
