We all get tired from work, that is a common. People are constantly needing some off time, some time that they can spend for themselves, a not so busy time which calls for relaxation and just doing nothing in particular. When you come into work and feel so tired at the upstart, what are you going to do next?
Well, you might as well go to your social media account and if your boss is a friend of yours, you could do well by subtly hinting to him or to her that you need some time to relax up. The best you can do is post something on your wall or maybe just message him or her directly at that.
Here are some I need a vacation meme that ought to do the trick. Use it and see for yourself if they work or not on your boss so you can use it again.
