I've been temping in my role and after many years, I was asked to go permanent or leave my role (they're making temp cutbacks). I decided to go permanent and my boss verbally told me to carry on temping for a few weeks, she'll contact HR, do a mini interview and she'd get it sorted. However, nothing was in writing. Now, after a good few weeks, I've been told I was unsuccessful at this 'mini interview' and they've given my job to someone else! Do I have any rights, as the job was supposed to have been mine, as discussed verbally?
