Holst and Company, a member of the Northwest Holst Group, has introduced flexible working hours for all its staff at its head office. It claims to be the first UK construction company to do this.The three-month trial period is being conducted with the approval of the overwhelming majority of the head offices. All 150 employees must be at their job during the“core time" from 10 a.m. to 4 p.m.，less a one-hour lunch break. They may choose arrival and departure times from 8 to 10 a.m. and 4 to 6 p.m. 150 hours have to be put in over each four-week period. Credit or debit time of up to 7 and 1/2 hours may be carried forward to the next four-week period. Hengstler Flextime recording equipment is being used for the trial. The managing director of Holst , Mr. Colin Cashmore , commented,“This is an exercise in responsibility. We regard our staff as very responsible people and it is only on this basis that the flexible working hours system can succeed.”He emphasized that if after the trial a majority of the staff was opposed lo the system, it would not be continued. If, on the other hand，it proved successful, the company would consider extending flextime to its other offices throughout the country.
All 150 employees are free to choose their arrival and departure times during the day.
A、正确
B、错误
【正确答案】：B
【题目解析】：由第四句可知，所有的150名雇员并不完全能自由选择他们的。上下班时间，而是从上午10点到下午4点一定要在工作岗位上,除一个小时午餐时间。故本题的说法是错误的。
