So last week at work, school call mid morning to say DS2 is poorly, they really feel he ought to go home. School usually are pretty robust at keeping kids in welfare and only really call if feel they need to go. DS2 was feeling sick and light headed. Anyway I tell my boss if I can leave at lunchtime after I do my mornings work. Its around 11am. get several more calls from school to say DS2 now being sick. Rush to try and finish off what am doing. Colleague says she will cover me for afternoon. Leave around midday. Anyway today boys says would i like to make up my hours for the afternoon taken off of take it as unpaid leave? I have never taken time off for kids illness before. I usually either bring child to work if not too unwell or have found cover. Also colleague that covered me was asked to invoice for her overtime but she said no its fine as we all cover each other in times of need and if she had to dash off she'd hope work would be fine with it. They tell her how admirable of you, thanks. So I am now making up the hours on my day off, that my colleague has covered free of charge???? Seems wrong?
