Hypothetical divisional question. Someone submits 12 months notice but he/she gets the job offer of a lifetime which starts in, say, 4 months time and is allowed to leave 8 months early to take up the new job. I've seen this happen many times. But - is that same person entitled to guaranteed employment for 12 months after submission of notice? What would happen, for instance, if their job offer fell through? Would he/she have to leave before the 12 months has expired or are they entitled by law to a full 12 months to work their notice? Any thoughts?
