I have recently started a job and unfortunately my father has been very unwell. He had a heart attack and on Friday had heart surgery. Is now in HDU. Tomorrow my work want me to go to another part of the country to provide admin support for a meeting (a number of other people in the team will also be going and could easily cover). This will mean I won't be able to see my father - and as I am the only person who visits he will be alone. If anything happens I will be the other side of the country. I have tried to explain the circumstances to my manager but she is adamant I should go. I haven't slept all weekend worrying about what to do.
