No offence to anyone working in a full time job, but when I was working full time, I always used to feel guilty of going and asking my manager for a leave if I wanted to go home, or take a weekend trip, or just take a break and sit at home for a day. Maybe I was not the smartest employee, and was always scared of asking for a leave or something. I was never just good at it. Of course, I took leaves almost whenever I needed it, but I had to think a lot before doing that. Plagued by guilt and fear that the other person would judge me as being a slacker, I would weigh the importance of the event and then decide if I should bunk work or not. Here the work schedule is slightly different.
No, you cannot bunk just like that even here. Because if you are a freelancer, you bunk one day, and you lose three students. But what you can do is plan your classes in a way where you can give off a holiday for a few days where you don't want to work. I usually take summer and winter vacations as a good opportunity to take a break. It actually does not even make too much sense taking classes because the class strength during this time would be half of what it normally is.
The only thing you have to plan in this whole holiday thing is where your money will come from. And if you can do that in advance, and also save up while the sun shines, you can pamper yourself to an amazing one week vacation... Guilt Free!!!
