I, as a [not so] 'umble ATSA111, [was an ATSA11, until (fairly recently) at Manchester], would whole-heartedly reccomend a smaller unit than LACC/LATCC or whatever the name is today.
Unfortunately, in the "Real World", you will be posted just where you are needed...

Depending on your Grade, ...O/T is
ATSA1/11/111, Weekday working, Time and a half
Weekend working, Double time
Bank, Public Holidays, Triple time
ATSA1V...Plain time, except for Sunday and and/PH...
As an aside, I have been an ATSA/ATCA for 40 years...

Would I change it?
Then....NO
Now...I would
seriously think abut becoming an ATCO, 'cos ATSA days are numbered.... at least at "larger units"
Good Luck, in which ever side that you choose....

DC10, nice to see that you are as sensitive as ever
