Are you dreading to go to work because of your colleague?
Is there a problem that you just don’t see how to resolve other than them or you leaving?
Has it been difficult to work with a colleague / staff / team member for a while?
Everybody spends a lot of time at work and we like our workplace to be peaceful and enjoyable. Conflict is part of life and work too. Learn new ways how to manage conflict, come and talk things out with support so everybody can focus on their work and feel good in the workplace.
Ask if your employer is willing to invest in resolving ongoing issues, they may give you time and pick up the invoice because most employers care about their staff wellbeing.
