I apologize if this isn't the right subreddit to ask for this kind of advice in, please redirect me if so! Apologies for the quick repost, I looked over it and saw the text was messed up so I deleted it to fix it haha.
I started a new job at a dog kennel about 3 months ago, part-time, split shift and on the weekends. By all means it's an awesome job, has to do with an interest of mine, doesn't ask too much of my schedule and gives me a steady paycheck which is great for obvious reasons. I was unemployed for about a year prior and the only thing I didn't enjoy about it was how random and sporadic any cash flow was, but I'm one of those people that has many different little side-gigs so it has always (thus far) worked out.
The only downside to this job is the manager. She comes across as very passive-aggressive and belittling; her version of 'training' is to half-ass or sometimes not even show you how to do something, and then make judgmental comments about the way I attempt to do it. She's blamed me several times for things that one of the other girls has done, even after I denied it (think along the lines of 'well it wasn't here before, so obviously it was you' stuff). By all means I feel like I'm constantly competing with the other, long-term employee; golden child vs black sheep and all that. It seems in her eyes this other employee can do no wrong, and I've already been set up for failure because of it. She's been very accusatory of me not knowing things that have never been taught to me, even though I've only been there for three months and I'm still learning.
When I'm not working alongside her, which is two out of the three days I work, everything is usually fine; unless I have to ask her any questions or attempt to contact her directly, in which case it usually takes her DAYS to respond. For instance, she had asked me to ensure that one of our dogs be given some medication over the weekend, showed me how to apply it, etc. However come weekend I could not for the life of me find it anywhere, so I sent her a message. She read it and never responded. This last week I put in a vacation request for two weekends and asked her to let me know ASAP if she couldn't do two weekends so that my family and I could adjust accordingly. I didn't hear a response, so I followed up with a gentle reminder message three days later. She read the message, didn't respond until two days after that, and told me that she had missed the vacation request as it had been knocked off her desk and had only seen it yesterday (funny, seeing as how I'd messaged her the day before that).
All of these things combined with the passive-aggressive distrustfulness has just really put me off the whole thing. I've spent the last couple of days I've worked with her avoiding her because I'd be lying if I said I wasn't really nervous around her. I'm a really laidback person at heart, so even though some of my family members are recommending a more confident approach (speaking up, ignoring comments) I can't really see myself doing that out of fear lol. (It doesn't help that she reminds me of my mother, despite only being about a decade older than I am).
When is enough enough?? My family all thinks I should just tough it out and keep the job, but the entire reason I quit my last job was because I was sick and tired of being belittled. I'm afraid that I'll miss the job itself, maybe even regret quitting it.
Any insight is greatly appreciated!
