Unions usually try to bargain for benefits as part of the overall package of remuneration for employees. There may also be fiscal advantages where non-taxable benefits are provided. Of course, whether the costs are borne entirely or partly by the employer can make a difference regarding their attractiveness to employees.
Benefits can be more cost-effective in that respect than raising wages and salaries.
Many of these benefits, while supporting the physical and mental health of employees and their dependents, can also help deal with situations that could adversely affect family cohesion. Many non-medical benefits that may aid employees with families can also be offered. Even a seemingly simple matter such as having access to a telephone for personal calls while at work can be a relevant benefit for employees with family responsibilities.
