Thank you. The way I read the contract is that there is a ‘core’ number of hours, which in this case is going to be the 19.3 hours mentioned in the contract. These would be the contracted hours of work.
The contract then allows you to either increase or reduce these hours. If you were increasing them, you would be required to give ‘as much notice as possible’ If you were reducing them, that is when the 4 weeks’ notice would apply. However, this reduction should only refer to the contracted hours, not any additional hours they have been asked to work under the above clauses.
You would otherwise be in a position where you need them working 10 extra hours one week due to increased workload, but then have to keep giving them these extra hours for 4 weeks just to bring them back down to their contracted level. Therefore, this 4 week notice period would only apply if you were reducing their core hours, not any additional hours you have asked them to work from time to time.
