Re work and short notice shift changes

[NCIS]

I work shifts and am on a relief rota which means I get to know my shifts at the most one month in advance.
One day next week I was rostered to work a 1800-0600 shift at my normal base. Today I get a text to say I have to work a 1900-0700 at a base 20 miles further away.
This means an eighty mile round trip(40 miles there and back). I have organised childcare based on my original shift which I have had to change and have the prospect of driving 40 miles after a long night shift.
Have asked if there is any possibility of change and been told 'no'.
AIBU to be very fed up?

YANBU to be fed up. What does your contract say? Is this a one off or does it happen often?

Whether or not you are being reasonable depends on what your contract says.

(but this doesn't mean I don't feel sympathetic,because I do)

Moving base doesn't happen as often as hour changes which happen every couple of weeks. I have been able to take holiday/emergency childcare leave before when I've been moved but not this time.
I'm on this relief rota until they put me on a rota line and this means I can be sent anywhere in the county, was promised a rota within six months but so far it's been 18 months.
I don't normally mind shift changes but the extra travel time and distance worries me, it's hard enough to stay awake driving home when it's 20 miles.

Yanbu. But we get our shifts the day before. Try living with that.

Paranoid, that's awful, what sector do you work in? How on earth do you organise childcare?

Wow that is unbelievably difficult to work with - partic Paranoid

I'm beginning to feel lucky after reading Paranoids post.
