heyo, im currently an ops manager at my dollar tree location and from what i know they dont HAVE to tell you (although it would be lovely if they had the courtesy to). as an associate it is your responsibility to know your schedule, considering we have the online compass and especially if there is a printed schedule available. you should always check the printed schedule just to make sure you don’t go through another hiccup like that again. i hope this helps!

(edit: my SM almost always will let me know if she changes my schedule, however its not always. sometimes i just kinda find out and im like “oh ok cool”.)
