Worrying that you are going to lose your job is horrible. Work is an important part of life as it defines who we are and puts food on the table. As soon as your job is threatened then your ability to support your family and your lifestyle is threatened too.
If you’re worried about your job then it’s important to understand that you have rights and you have options. There are processes that your employer must follow before you can be dismissed. Even if you have had a slip up and have done something wrong, losing your job is by no means a done deal.
