Leave my job for this reason?

[malteaserlady]

I'm on a zero hour contract and I do like and enjoy my job.
The thing is it is every single Sunday, with it being zero hour the boss wont even accept me saying "I can't work X day" i have to fill in a holiday form 3 weeks in advance to be accepted or rejected.
I have young kids and asked if I could work every other, but no.

AIBU to leave a job I otherwise enjoy for this reason?

If you’re on a genuine zero hours contract there should be no obligation on you to accept any shifts.

Yep, zero hour should mean that there is no obligation on either side. Sounds like your employer is abusing it.

I would start looking for another role if I were you.

This is what I thought but apparently not, this is a message we got

Holidays - We need 3 weeks' notice for all holiday requests, these must be emailed to (my boss) and once approved you will receive email confirmation back. Only two team members can be off at any one time. If you require a holiday which is already booked out by another team please speak with (the manager)

I don't know whether to just got for a contracted week day job as part of the reason I took this job is I expected it to be flexible. I'm one of the only members of staff above 18 who works every single Sunday. When I said can I maybe do 2 week days one week and a weekday and a Sunday the next on rotation he basically said no, Sunday is my day. I can book them as holiday if I wanted some off.

Paid holiday is different- he had every right to set rules about that - although again, this rule seems to go against what is stated in law. But not accepting a shift is just an unpaid non working day.

I would definitely look for another job, your employer is taking the piss.

Just send him a copy of your contract and don't go in.

If you want to quit just quit for any reason or none

I've never had nor seen a contract, we've all asked several times (I've been there over 18 months) and they say they will sort it but nothing comes of it.

I don't get paid holidays, just 12% (I think) added to my wages each month as "holiday pay"?

You need to call ACAS for some advice. This should be referred to the Employment Tribunal, I would imagine.
Zero contract means there is no obligation to accept shifts. Your employer may still terminate your contract if you refuse but they certainly can't insist you do them.

Your boss is taking the piss and has to give you a contract.

Try googling "uk employer refuses to give me contract".
