For those who have taken the time to provide useful and constructive advice to me, thank you very much - I really appreciate it.
I've thought things over last night, and to be honest - due to personal circumstances and some things I have had to overcome in my life, I really don't have the fight for this. I just don't.
I've given myself until April to find a new job, if it means that I need to drop down to part time hours to accommodate the request to be in 5 days a week but still doing the school runs, then I will do that temporarily if I am allowed to.
I have someone very good in my life that will help me with the drop of income temporarily so that is also a help.
Everyone is replaceable in a job, I know I am very good at my job, my productivity has never been affected by WFH. I don't take the p*ss. I am flexible with annual leave and having to change WFH days and have previously come in on my WFH days and worked 9 - 2 because that is what the service requires.
I am not someone who wants to play the system.
I am not someone who wants to take the p*ss.
For the user who said it's very annoying when people log off for 30 minutes to do the school run. Why? it doesn't affect you? You don't have to pick up my work? so why does it annoy you when it has zero impact on you whatsoever.
Anyway, thanks to those who have taken the time to comment constructively and those who have provided feedback on the likely outcomes and to those who have been empathetic towards the situation.
