Employees have a variety of rights related to time off if they're injured or fall ill. For example, in workplaces covered by the Federal Medical Leave Act, workers are allowed to take up to 12 weeks off without losing their position in a company. The leave is unpaid unless PTO time can be used to cover it. Employees may also have rights to file a workers' comp claim if they're injured on the job. All of these laws cover different situations and types of employers, and an employment attorney can help you understand what rights you have.
