Quitting a job?

[Anonymous]

I’ve been working at this particular job for 6 months and I absolutely LOVE it. It’s a office administrator job with a possible promotion to an office manager.
So before I’ve gotten this job, I understood it’s a part-time job. I said I could do it and got the job offer.
Well since they needed the extra help to work on projects that were long overdue, they needed me full time.
As I thought I was guaranteed a full time position, they’ve had a meeting with board members and all voted me to become part-time as should.
So now I’m back to part-time and my rent rate went up $100 more and will increase again once the lease is expired.
As a single mom, I can’t afford a part time job, however I don’t want to leave the job I already have since they’ve trusted me and doing a great job.
I’ve tried to find another part time job but it wouldn’t work out as much as I want it to.
So my question is, how do I put in my 2 weeks without them taking things personally?
They definitely don’t want me to leave but I can’t afford a part time job

If you're going to give two weeks' notice, they won't take it personally. Nor should they. Make sure you have another job lined up and then give them your notice. If they ask why, you politely tell that that you love the job and would stay if it was full time but that otherwise, you're obligated to earn a living salary and that part time doesn't work any more. It is possible (not a guarantee obviously) that they may then decide to keep you on. The cost of hiring you full time may be less than retraining someone. But make sure it's not an empty threat -- have the other job to go to.
