Part-time working and holiday pay

[CocktailSausage]

I work 3 days a week at an average of 8 hours for a company that I have been employed for 9 years.
I am payed hourly
I was working full-time up until last year when I returned from maternity leave.
The management have recently changed and we've had major cut backs on staff.

Last year my holiday entitlement was 16.8 days of which I was paid for 8 hours per day of holiday or 24 hours of holiday pay per week worked. This was equal to 5.6 weeks.
I believe this is the correct holiday entitlement for me.

This year my employers have changed my holiday entitlement to 14 days of 5.5 hours per day of holiday or 19.5 hours of holiday pay per week worked.

This does not seem to work out as 5.6 weeks. This change has been made to all on part-time.
What I believe they have done is cut the full-time holiday entitlement in half and are claiming they can pay us our holiday entitlement like this.
As far as I know this is unlawful.

So other than talking to human resources - what can I do about it?

Your help is gratefully received.

If you work 24 hours a week then by law your holiday entitlement should be 134.4 hours annually.

From what you've said they've cut your holiday to 77 hours. They can't do this for three reasons.

1. It's below the statutory legal minimum which is 5.6 weeks' holiday
2. They are not allowed to unilaterally change your terms and conditions of employment without your consent which you haven't given.
3. They are treating part timers less favourably than full timers which is illegal.

Put that in writing to whichever senior manager/director is appropriate, copying in your own manager and HR.

Thank you flowery. It is what I thought.
