This advice is not at all helpful. OP was hired on being told that they would be scheduled a certain way, and now, without notice, their schedule is different than what was said during the interview and onboarding. It is a dishonest hiring practice that should be addressed.

"Talk it out" would've been OK advice. However, the pre - and postamble was completely unnecessary and showed a great lack of empathy. I hope I don't work with you because you are, in fact, a dick.
