How would you deal with this?

[time4me]

I am a very reliable employee with an 18 year old son who is severely disabled.When I text my Line-manager to say he was ill and could I work from home today,she text back that I could as a one-off
DH also has time off to look after son.
I very,very rarely have time off either for myself or son.I know other members of staff do for their non-disabled children.
My dh says dont worry about it,just forget it and if disabled son is ill in the future just take the time off and dont worry about it.Easier said than done!
Generally I get on with her and I don`t want there to be an atmosphere,how would you tackle this?

time4me, what sort of organisation do you work for? I'm with the NHS, who have a policy of "carers" leave, for any sort of domestic problem. My brother who works for a large bank also can take "family days" which are not exclusively for when little kids are ill - he took one when his DH had a bad migraine and couldn't look after their DD. Does your employer have a personnel dept where you could look at policies to be aware of what you are entitled to? Also I'd recommend citizens advice in case you aren't entitled to paid time off. I'm sure there's some regulation about unpaid time off for a disabled child under 19. That doesn't sort things for you, for long, I know, but its worth looking into. All the best

Thanks theheadgirl.Im in Education and it is inflexible but I am entitled to time off so long as its not unreasonable,apperently.
Also I did make alternative arrangements so its not as though the pupils were stranded.Everyone else was sympathetic.No I think she has them on her,having a bad day,in a bad mood,whatever.I think I am seen as a soft target and word will swiftly get round the office that I have sort of received a reprimand,to save her the job of telling everyone she doesnt approve of time off for kids!
Can I emphasise again that I am extremely reliable.This is why it hurts
