Whether you work a 9 to 5 or the night-shift, our jobs and workplaces have legal requirements all around them.
Sometimes these could be the contracts of employment that set down what an employer expects from an employee, and vice-versa.
In other cases they might be health and safety regulations in a workplace. Or they could be legal requirements to treat all employees fairly.
Whatever your situation if you start to have issues at work it might help to work out what the legal position is.
