Final answer:
Flexible hours to assist workers with elderly care responsibilities are a tangible form of social support, allowing them to balance work and family obligations through flexible scheduling.
Step-by-step explanation:
Flexible hours that help workers who are looking after elderly parents take them to their doctor's appointments are indeed a tangible form of social support. This kind of support falls under workplace support mechanisms, which include flextime, understanding supervisors, leave with pay, and the possibility of telecommuting. Flextime specifically refers to an arrangement that allows employees to craft their work schedules around the demands of their personal life, thereby giving them the opportunity to fulfill family obligations. It is a substantial way to reduce work-family conflict and, as such, constitutes a practical support that can make a significant positive difference in the lives of employees.
