manager is ridiculous - Sales Associate APM Monaco Employee Review

-The manager constantly changes my shifts at the last minute without telling me. -She posts 20+ irrelevant messages daily in the group chat and expects us part-time to reply to each of them. -Always push us to stay overtime just because she does so. -Acts like she is busy but does nothing productive, most times she just messes up our stocks, and we are always lost when serving a customer.
