Strictly speaking they can sue you for any damages they can prove plus compensation i.e. you leave without notice and they have to make arrangements to cover your work. Although the amount they pay out in wages/overtime might be the same as it was to you, they can claim costs & compensation for the hassle of having to do so and the potential disruption it caused.k979aaa wrote:What is the punishment for not giving a week or a months notice given that at most we are paid a week in hand in any case apart from overpaid holiday entitlements they could claim back as the business is run on a shoestring so if anyone goes sick or just jacks it in it is the same cost to said business?
The chances of them doing this are zero as it would cost more to do it than they would recover.
To answer the OP's question, I'm pretty certain they will want you to work the full notice period as anything less causes more work for them. Make sure you put your notice in writing giving a final date that you choose. If you agree to any different arrangements then make sure you get it in writing e.g. longer/shorter period of notice. It sounds like they're already taking advantage of your good will so be prepared to be squeezed even harder....or you could say no and just do the job you were contracted to do.
Good luck
