This is in the UK

Part-time employees have the same statutory employment rights as other employees. You do not have to work a minimum number of hours to qualify for employment rights

Anyone can ask their employer for flexible work arrangements, but the government has introduced a statutory right in order to encourage applications. Provided you are an employee (but not an agency worker or in the armed forces) and have worked for your employer for 26 weeks continuously before applying, you have the statutory right to ask if you:

have a child under six or a disabled child under 18
are responsible for the child as a parent/guardian/special guardian/foster parent/private foster carer or as the holder of a residence order
are the spouse, partner or civil partner of one of these and
are applying to care for the child
From 6 April 2007, you also have the statutory right if you:

are a carer who cares, or expects to be caring, for a spouse, partner, civil partner or relative or who lives at the same address as the person being cared for
Under the law your employer must seriously consider any application you make, but they don't have to agree if there's a good business reason not to. You have the right to ask for flexible working - not the right to have it.

as bush/cheney have shown, there is a larg gap between what is moral and ethical and what is legal. (of course they ignored the legal aspect too). as mean spirited as it may be, the employer can probably dictate (there goes bush again) what hours the employees work.

Companies are required to allow its employees only to work when its convenient or when they "feel like it". If an employee has other stuff to do, they don't have work and the company still has to pay them.

Her services are at his pleasure. If she can't or wont do as he requests she has no rights to hold the position.

The liberals are working on this as we speak. When they get the bugs worked out, I'm going to demand a job working from 12:00 noon til 1:00 in the afternoon. I'll demand they pay me $250.00 an hour to start. And them sorry devils better dang sure give me an hour off for lunch.
