I work in a professional field for a large organisation. In the space of just a few years my workload has increased dramatically. I have been given one extra member of staff to help which does not make up for all the extra areas I am now covering. I was not involved in the recruitment process. This person has been given all the training and support they need but they are not willing to stand on their own two feet and work out any problems in their own and they come to me every single time. I get sent multiple screenshots of emails, worksheets every single day. He even asks me how he should word emails. He was hired to provide me with more capacity but I feel like instead of helping he is adding to my workload. There have also been multiple times he is showing as away when he is supposed to be working. I can’t go on like this anymore. This job has taken a toll on my mental and physical health. I have lost all my confidence and don’t feel strong enough or confident enough to go out into the job market and look for something else. I’ve stopped looking after myself and I look awful. I just don’t know what to do and feel trapped. I’ve tried talking to my manager but to no avail. I feel totally stuck in this situation and don’t know what to do.
