5 hours a week (2 hours on a Tuesday, 3 hours on a Saturday)
All nice and well first few weeks/months then can become very repetitive and tiring.
2 - 5 hours a week
5 hours a week ( 2 hours on Thursday and 3 hours on Saturday).
Very flexible, 6 hours a week
The working hours are excellent because they're flexible. However, there is a chance that you might not get the dates you want but the majority of the time you do.
Fixed but very do able and accommodating.
