Hi @Green_Ghost
I am sorry to hear what you have been going through. You are not the only one with a bad manager. I work in customer service too and I did this to help me when my relationship with my manager wasn't great.
1. I talked to everyone else, and I got to know others in other departments. This was a way of building positive relationships with others, because not only would they say good things about you or how hard you work, but it also helped me get into doing other jobs around the store. This helped me reach out to other department managers to get different shifts elsewhere and find people I could trust. Some of my best friends are from other departments and I can get things off my chest about work to them with the understanding.
2. Look busy, your manager might be someone who wants you to look busy instead of standing around doing nothing (even though aren't I get it). Clean the area you're in and around you, face up stock etc.
3. Set a positive mind before going to work, I had previously had a hard time working coming into work and it made me smile less and whatnot, so I set a routine to set a positive mind so I could come in with a smile and whatnot. Mine is now just listening to music I enjoy but it is used to mindfulness techniques and deep breathing so I could deal with what I could deal with at work.
4. Ultimately if you need to and feel comfortable discussing it with their manager if possible, most of the time they have someone above you or even reach out to the people and culture/ HR team for advice. They can often provide fact sheets more likely when dealing with "conflict" in the workplace and should be confidential at all times. It might help understand what you are capable of doing and help you address these things with your manager. If not the option for shifts elsewhere could be presented to you.
Just remember that it is a temporary step towards something better and references don't always have to be from the job, they can be from volunteer activities, community participation, university teachers etc.
