To put your mind at rest mts1, I've also worked for a short period for Airservices and despite what may appear dissatisfaction with NATS i can assure you that Airservices are worse.
Remember also that this thread is largely retired people comparing "the good old days" of our youth. So the grumbles you're reading should be balanced by the opinions of younger people currently working.
(edit) wow 4 posts and I'm no longer probationary.
