Thanks to all for their kind words.
My notice formally went in today and I'll be finishing late August. I should have alternative employment secured by then.
After then, I will be leaving the site, as I have nothing to offer outside of ntl and in any case need this to be a 'clean break'. That is no reflection on anyone at the site or the management team here, who do a fantastic job. It's just the right decision for me.
However, I'll still be here and at ntl until then, and will continue to assist wherever I can up til then. Obviously as the date gets nearer I'll take on less because it might spill over to september when I won't have any access to the ntl systems.
I shall deactivate my own Harmony log in on the last day. That will be sad
When I've left other jobs, I've invariably arranged to 'phone in sick' on the final day because it all gets a bit emotional and I prefer to give it a miss. It will be a truly sad day as I really thought I'd be able to stay at ntl. I wanted to.
