Hello to all HR proficient people on this thread,

My father is sick and I really need help with employee problem. Everything seems to be falliing apart, i'm trying to keep the business in one pc...

Our offer letter states:
-3 months probation
-at company's discretion, probation can be prolonged for another 3 mths.
-but does not state that after three months, permanent staff position is automatic.
-permanent position resignation notice is 1 month.

This employee (RM1200+ salary) was told he is confirmed before the end of the 3 months probation. He received an increment on his 4th month salary. But father fell ill so there wasnt any follow up in paper. I read past HR record, our company practice has always been a one-way letter to inform staff confirmation.

He resigned, wanting 24 hr termination based on probationary entitlement. I know there is no point to make him stay if he is so adamant. What I wish to know is:

-does he owe the company 1 month's notice worth of pay?
-do i need to pay him the 10 days he worked for in the 5th month?
-can i rreport him to any authority about his misconduct?

The whole reason why is because I can't afford to lose any more employees as there are only 3 of them to help me hold the fort. I hope that I can put an end to their bullying me. I have quickly sent another 2 confirmation letters after this discovery. I also have to find time to go to and fro the hospital. Please help.
