i've worked four shifts at my new job, which is just a shitty retail clothing store. i haven't been scheduled for all of december, and my manager never responded to my email when i reached out to her. she edited one of my time punches a couple days ago on the scheduling app, so at this point it's not like she just "forgot" to schedule me. i picked up an offered shift for this week for a little extra money and i guess it comes off a little petty too. is this just their way of saying they don't want me and getting me to quit even though i just got hired like two weeks ago? should i even bother leaving a notice if i go? trying to find work during the holiday season suuuuucks.
