Some of the comments are a little harsh I feel. From what I understand, YEG Centre is working 2-man sectors (i.e. Data & radar positions) as single man sectors for a large proportion of the day due to lack of manning. I'm not sure if other centres have the same policy/problem. There are some pretty tired people at the Centre that probably wouldn't choose to work the maximum amount of overtime - if they had a choice. This has a knock-on effect on ability to train and the downward spiral continues.
Maybe, some people on here, if they use the facility regularly, should keep a day free and visit the centre. They might have a better appreciation of what's happening 'behind the scenes'.
My rant over!
