Why still everyone on holiday??

It's still quiet on the road today. I just called up the national library, and guess what! I called yesterday at 530pm, there wasn't anyone picking up. I called again today, and enquired when did they start working? Surprisingly, they told me yesterday! As I know, they opened till 7pm on weekdays. Then, they said that they closed at 430pm yesterday. Hello.... as a goverment institution, how can one decide to work at their own expense? 3 out of 4 canteens in my working place are still not opened up till today! Oh, come on. Holiday is holiday and working is working. Be professional. How can they expect people to follow their time of working when they are so unpredictable? It's really testing one's patience. Breathe in, breathe out. C'est la vie. That's life here! Anyone wanna say something? Waiting...
