A family member of mine is applying for a part time job very similar to the one she does now. But it is 5 hours less per week so financially she will lose out. She's applying because it's got better prospects and in walking distance from her home. If she is successful with the application can she ask if they would consider upping the hours slightly? Or is this a big no? Obviously the job states the hours and salary. But one of my friends recently did the same thing and got her hours increased by 5 per week so I wondered if it was unreasonable to request this or not?
