LOL. depends on lots of things. like, if its cloudy outside, how traffic is, etc
but seriously, my store seems to make up the rules. i thought it was SALARY can have them, non-exempt cant. but of course my Sr.TLs carry them with no problems. Most of the TLs do as well. out MMB TM wears hers on her belt with no problem whatsoever. but if i (regular elec TM) use mine to even check the time, all hell breaks out on me haha. the other elec TM "technically BRAND tm" uses his on the clock to help guests look up info and such and texts, never heard a cross word about that.
just depends if your higher ups like you or not, i guess
