8-2 The benefits of a paid vacation Taking a paid vacation is good for everyone. Not only are regular vacations good for the work-life balance of the individual employees， they also increase productivity， which is great for business. Vacations don’t need to be long to be effective. Sally Harper， a professional psychologist says: “Some people believe that a vacation is only worthwhile if it’s for two weeks or longer. In fact， taking several short two-day vacations each year can be even more energising. You don’t need to spend lots of money travelling somewhere new. The important thing is to try something you haven’t done before.” Sally continues: “It’s fine to stay at home， but go on a hike， or go swimming， you will feel better. Don’t spend your vacation cleaning out your kitchen closet， as this will not help you to return to work feeling recharged!” When you go on vacation， take a complete break from work. Sally says: “It can be tempting to respond to emails， so you don’t fall too far behind. If you do this， you’re not on vacation-you’re just working somewhere else.” If you’re still not convinced about the importance of taking regular vacations， think of the health benefits. Taking regular time off will improve your mental and physical health. You’ll return to work feeling relaxed and find it easier to get along with your colleagues. Better start planning your time off work now. And if you’re an employer， make sure you encourage all your employees to make the most of their vacations. 77.
