Most employers have extensive policies on how to take parental leave at their company. While the general principles cannot be watered down or altered in any way, there may be specific notification requirements that the employee should be aware of before taking a leave. Union members are covered by collective employment contracts that set wages, benefits, planning issues and other working conditions for insured employees. Employers need to think carefully about the needs of the company before creating an employment contract. If, for example, they may have to terminate an employee`s shift, the appropriate compensation and notice period must be included in the employment contract. There is a wide range of clauses that are usually included in employment contracts, but are not required by law. .
