If hired how much time do you need to give notice for your current position meaning

I would say in this situation one should give at least one month's notice or more if available as the more time one gives the better relationship one will preserve with the old employer as it is not good to burn one's bridges as one never knows if he/she will have to go back to the old employer later.

If someone is hired, the how much time he needs to give notice for his current position must be a month or 30 days notice, this is according to the law, in order to clear out his accountabilities in the company. However there are times that the period maybe shortened to 12-15 days if needed.
