Completely agree with the previous sentiments. In my case, I did the 'done' thing and continued to work for my previous employer in order to complete my full notice term.
Actually my previous would have let me go early, but I thought I should complete my contract. BA dropped me off my first course and I started about 6 weeks later than originally planned......the result about 40 places further down the seniority list for life!
I actually ended up going to long haul straight away instead of the short haul offered on the earlier course date. Fantastic for my life style now etc but looking into the future, my career choices will always be behind those who started on the original date.
Also, for those who wish to commute, when the push comes to a shove, equal priority standby pax are given seats based on their date of joining.
Basically, we should have all joined at 18 years old!
