What happened last year was a Secondment. I may be wrong but i do not think that what you are talking about this time is a Secondment.
Not backing any particular side but i was just trying to ensure that the correct facts are used before people start banding around accusations of what is fair & what is not. Secondment is completly different to a "chaps so & so are recruiting if you are interested in it" message.
I do not know any of the details but if one of the bmi folk who has taken this further would like to correct any of my errors, i'd happily stand corrected.
