Your employer could start formal disciplinary action against you if they have concerns about your work, conduct or absence.
Before taking formal disciplinary action or dismissing you, your employer may try to raise the matter informally with you. However, they can go straight to their formal disciplinary or dismissal procedures.
Disciplinary procedures are a set way for an employer to deal with disciplinary issues. They should include a disciplinary hearing where you’re given a chance to explain your side of the story.
There should also be a chance to appeal any disciplinary action your employer decides to take.
