Really not sure what to do about job situation

[Bluevioletindigo]

I've been with a company for a few months, it's paid hourly and I was averaging over 30 per week. I requested to be transferred due to a bullying manager and I have been put in a new department now.
The manager and all the staff are so lovely and kind, really professional and have gone out of their way to help me.
The only issue is that they can only offer me 16 hours a week, some weeks if there's overtime I can get 18-24 but this is not guaranteed.
I have a second job as a supply teacher but obviously this is zero hours.
My hours are on a rota basis and I have to be available 7 days a week, so I can't really commit to a second job.

I've interviewed for a role elsewhere which is 20 hours guaranteed and on fixed days. it would give me £180 per month guaranteed extra and I'd be able to find a second role around it.

Really not sure what to do, I feel really guilty towards my current role as they've gone out of their way to help me and I don't want to mess them about. But I've had a huge salary drop. What should i do?

I know money isn't everything but it's difficult for me financially now.

Take the new job. It’s a shame but I don’t see what else you can do.

If you are offered the new job take it. Express gratitude for the support from your colleagues & tell them you appreciated them but really need fixed hours- surely anyone would understand.

Don’t give more to an employer than they’d give to you. Businesses would always put their needs before an employee so I recommend employees always put themselves first.

Take the better job, no guilt.

Thanks everyone, I know it is the right decision.
Just feel bad as they have spent time training me etc, but I'm sure they would understand about the hours.

If they wanted to secure employee loyalty they would offer work contracts that don't demand (more than) full-time availability but don't pay living wages. I sound glib but that's the reality of your current job - not many adults can afford to work like that so your employer shouldn't and cannot expect loyalty. I say this as a people manager in a role where we have a candidate shortage. The only time I get HR discretion is where candidates are repeatedly walking away, jobs have high turnover, and there's a business case to justify higher spend. It's ruthless.

Walk away with as much goodwill as you can from your current job but get into a stable, more financially secure job that works for you. You shouldn't be thinking twice unless you need a good reference and think it'll hinder your move.

If they really wanted your loyalty maybe they should have dealt with the bully properly.

I totally agree.

The bottom line for any company is 'the needs of the business'.

Do know the specifics of the bullying manager but, if they were so great (the company as a whole) maybe they would not have been employing that person?

Obviously difficult to judge your situation, bullies tend to think of themselves as "just being assertive"

They spoke to the bully and she was requested to issue an apology, but I just said I wanted to move.
I was contracted for part time hours when I started but was told that I could do full time hours so quit my main job for it.
The current service simply has enough full time staff so they said that's all they can offer me.
But £600 per month then £75-£150 per week on supply if I'm lucky isn't enough to live on and I do have to think of my finances.

Thanks for helping me to make the right decision.

Plus no supply work during school holidays so I lose money there too.
