Going for new job as I need a change. However bonus due in April as well as a referral bonus and 5 year service award. Had first interview and new potential employer wants to meet me asap. Theoretically they should give you the bonus if u work till end jan but I know they've not honoured this in one case. I know I've not got the job yet but I know someone in this company who is recommending me. How can I ensure I receive my bonus if I leave?
