I need a list of the aspects of employment that are controlled by the law.
There are a number of employment aspects that are covered by legislation.
For instance, health and safety law concerns the work conditions, safety standards, health insurance, the length of working shifts (max of working hours), minimum wage, and sick pay.
Among other groups of laws regarding the employment are anti-discrimination protection (gender, race, disability, age); personal data security; different kinds of leaves (sickness, maternity etc.), vacation schedule and many others.
It’s hard to say about all of them at one. You’d better appeal to some consistent paper on this topic, like this one.
