hi guys i've been reading the thread but have not found an answer to my problem

situation

i'm planning to resign asap i've got another job waiting for me on the 1st of april ... i have not signed the thing and i can actually get an extension on the commencement date ... my salary is 3k gross and net is about 2.6k my company is small and has no HR department but it is a sister company to a bigger entity base on my contract, i have to give a 1 month notice ... my plan is to actually take 2 weeks off to work on my own business .... so the thing i am worried about is

a. if i quit now and i get my salary on the 31st and then don't come in from the 1st of april onwards ... can they sue me and will the go through the hassle of suing me for 15 days of salary?

b. if they don't give me my salary on the 31st, can i sue them and will it be a hassle for me?

c. if i just give a 24 hr notice on the 31st, what are the consequences?

sorry guys if my questions are vague ... really need help thanks
