I'm in a tricky situation and could use some advice on what to do. I'll try to be as detailed as possible without giving out identifying information.
I have 2 jobs, one retail position and one skilled trade at two businesses owned by the same person. She and I have known each other for about 10 years, and she is like a friend/mother figure to me. I started working at the retail store she opened and continued while going to school for my trade. Once I finished school, I split my time between both places.
Since then, I have grown increasingly unhappy with working at the store. I make 3-4x the $$$ doing my skilled trade and I get to make my own hours. I am very happy doing my skilled trade and have been slowly trying to cut my hours at the store over the past year to focus on my trade.
The problem is the store is not doing well, there is high employee turnover, and they rely on me heavily to basically manage the store for a clerks pay. Because the store is not doing well, the owners have been forced to work their other jobs in order to pay their bills. So they rely on us employees to work at the store. Another employee quit and I was told I had to pick up some of her hours on Fridays since I don't typically have clients on that day. I have been using that Friday as a much needed day off for the past few months. Now they're telling me I will have to pick up some Saturdays as well.
I like making other people happy and I like making everyone's lives easier, but it's starting to feel like it's at my expense and I'm not okay with that. My anxiety and depression are creeping back and I think it's partially due to my working at the store. I get calls from the owners and other employees on my days off (and while I'm on vacation!!) because they need help with the register or finding something in the store. I feel I have far too much responsibility for my pay and they rely too heavily on me to keep the store running.
I want out. I want my life back. But I don't want to jeopardize our relationship or my job at the trade business. Me leaving the store would be a hard hit to the owners and their business so I feel guilty for wanting to leave. But I'm also miserable and my personal life has been affected because of it.
How do I quit the job I hate without risking my position at the job I like?
UPDATE: Hi everyone! Thanks so much for your answers. I'm not "good" with words so you guys gave me a lot of great advice on how to properly convey what I'm feeling. I spoke with my boss a few times in the past week. They were going to cut another employees hours but told me I would have to keep mine- so I responded that after taxes and paying my dog walker, I only take home $7.00 per hour at the store and it's just not worth it to me. I told her that I will not work Saturdays and neither will the other employee, so she needs to keep those hours. By a stroke of luck this wonderful customer walked in later in the day and said she would be thrilled to work at the store, but ONLY if she can work full time (like 6 days a week). This would leave 1 day for the owners to go in and do paperwork, run the store, etc and the other 6 days they can do their other jobs. This would be the solution to all of my problems so send lots of positive energy and hope she follows through. I helped my boss put up a job posting online so we always have that as backup if this girl decides not to go through with it. But I think she would be a great fit for the store so I hope it works out. I'm looking forward to doing the job I love full-time! Thanks everyone!
