I work in healthcare and i have been in my job a year I have loved lots of aspects of my work, however the environment has become increasingly toxic and unsustainable. This has been caused by only a small amount of individuals, but had a big impact on me (think workplace bullying, passive aggressive manager, name smearing) In addition I have had a very hard year personally with health scares and a parental death.
I took some time off as a result of this and have found and accepted a new position. I am very much looking forward to the fresh start. I am handing in my notice tomorrow and feeling nervous about it. I am concerned about my boss giving a poor reference and also that my absence could count against me and my new job offer might get recinded.
YABU - it will be fine people move jobs and the reference will be fine.
YANBU - you should be worried about job being rescinded if these things flag up.
