Talk about chickens coming home to roost.
I remember that I vowed NEVER to give up my UK licence for one administered by an authority so cosily located in my employers pocket, not because I had the foresight to anticipate this, but because I didn't want aforesaid employer to have undue influence on a licence/medical that I needed to remain employed.
My time there was up before it became an issue, and it surely would have done.
Sympathies for those who were FORCED to change licence (Yeah, I know,nobody can be forced
you really believe that ? ) & "told you so " to those who acquiesced gracefully.
