Hope you realise from my Post that Management were aware my DH was hospital
Yes, you keep mentioning it...
Emailed me back to say that’s fine but they would have preferred a phone call as they got the email after my work start time.
...but they clearly still want you to call in and have told you so.
and I think I did more than necessary to contact them
On what planet is two missed calls 'more than necessary'? It's literally the bare minimum.
However I do think that as I did try contacting yesterday and this morning by phone it’s unreasonable of them to suggest I try phoning instead of emailing.
No, it isn't unreasonable. That's their policy. And from the perspective of someone who's been in your bosses shoes, it seems like you're making a deliberate effort to avoid speaking to them on the phone.
You say you can't keep calling as you're with your husband waiting to speak to Doctors all day, but you've got time for MumsNet 🤷🏻♂️
