not a nice thing to do, as u will deduct from her annual holiday and she would rather see her relatives for more days rather than sit in HK doing nothing. Her friends do not have extra days off. She will be very bored.
I agree. What I did before when I went to Singapore was:
1. Write a HUGE list for her to finish before you come home.
2. Tell her you allow her to go out for 2 hours @ day if she can finish her job.
3. She will have to finish those outstanding ones if she can;t finish themm by the time you return.
Mine did well.
