How long should I stay at this job?

If I’ve interpreted your text correctly, you’re appreciative of the position and its potential except for the extended work week. Work-life balance is incredibly important; so only you can determine which carries the greater weight at this point in time.

Is there any chance you could discuss with the boss the possibility of bringing on another part-timer to allow you more time off, explaining to him/her how deeply you value your long-term experience there?

In brief, I’d say wait it out and try your hand at crafting a better schedule for yourself. Good luck!

The six days and every Sunday is completely unreasonable in my opinion. Only you know how long you can keep doing it for, but it sounds like you are getting towards the end of putting up with it.

Will you give up some money to hire a third key holder? Maybe if you pose that to your boss he will consider it. I assume you work for a salary and don’t get overtime pay.

I was thrilled to find part time management jobs, they are so rare. I bet there is someone out there who would want the job. You could only schedule them when there is also a knowledgable sales person. That way it does not have to be someone who comes with strong experience in the wine business, they just need retail management experience and have references that they are trustworthy.

I would look for another job if your boss won’t entertain some sort of a solution. Working you 6 days a week unending demonstrates he doesn’t care how hard he works his employees. Maybe he can work all those hours, but most people can’t. I am not even talking about wanting to have time to smell the flowers, I mean physically and eventually mentally I find it to be abusive.

Assuming you have no special employment contract with your employer that includes a “non-compete” clause, why not consider starting your own business in the industry?

Before she started her food cart business in Wisconsin three-and-a-half years ago, my daughter was working as an assistant manager at a pub near Madison. She talked with her boss there and let him know that she was going to be getting into her food cart “as much as possible” in the spring of 2010. That was pretty much the equivalent of giving her notice there, but because of the good relationships that she had built up, they told her she could always come back if her startup faltered or failed, and in fact she rented their kitchen space (since the food cart rules in Madison require food preparation in a “commercial or equivalent kitchen” which she didn’t yet have) in their off hours for her cart business.

Maybe your own plans haven’t included “your own business”, but if I were starting over again and had the energy that you obviously have, I would think of nothing else. So start making plans in that direction, maintain your excellent reputation where you are – including not working your business while he’s paying you to work his! – and use your current job as a springboard to a career that you control totally.

I think you should have to wait there & learn new things. Its better to learn there anything as compare to change your job.

Getting experience from more than one source is a good thing. You have done that. What you need to do now is build stability. Now is the time for that. If you feel that staying will evolve, improve, go forward, then you should stick with that direction. Six day weeks are hard sometimes, but it sounds like it will become wort the doing.
I worked a factory job with ten hour shifts and three day weekends. I was in the Navy, where I put in five weeks without a day off, fourteen hour days, I got one day off and went right in to three more weeks no days off. I did a 24 hour shift once with one thirty minute break for lunch, no other breaks. All this was doing a highly physical job. (I was ONE TOUGH CHICK!) There are all sorts of scenarios out there. All have their plusses and minuses. The plusses are getting increasingly difficult to find. Develope loyalty and trust between you and your employer. That will go a long way. Try this to see if it will help. Open a special bank account. Call it your sixth day treasure. Every week, deposite $20. into it. When you get to work five day weeks again, that account should have enough in it to get a special reward for yourself. As the account grows, you might find yourself feeling so greedy, you won’t care about that sixth day anymore. You’ll just be excited about watching that balance grow.

I’d say stick it out. Really. That’s how you end up being Somebody, because you’re willing to go above and beyond…....

What a coincidence. Logged in to ask a question about staying in my job and saw this. What I can say is I got it worse than you. Been working part-time for two years hoping to get a full-time position but it’s not happening and my supposed superior is “insane”.

You know what you want and you are, for real, getting closer to getting it. It’s not gonna be forever anyway so I suggest hang on to it. If your friends and family are fine and will be fine while you prioritize this career move, that’s a great practical and logical choice.

So, @Haleth, what did you decide to do? How did it work out for you?
An update would be helpful. :-)
