Overtime Rate

[JBW1366]

My friend is on a 33 hours a week contract and she did some overtime this week - which has an overtime rate which kicks in when she works over her contracted hours.

But her employers have stated that as she had a weeks leave / holiday earlier in the month - she wouldn't get overtime rate for this overtime - as she hasn't met her required hours for the month due to the leave / holiday?

Is that correct?

Doesn't the holiday count as meeting required hours? in that case it is not beneficial to have holiday? or actually to do overtime in a month when you have taken leave / holiday.

Any help gratefully received
