I am not going to work today.
Why aren't you going into work? Are you on a strike?
We are sick of poor pay and working conditions.
Striking is an act of importance and is not done easily. Wanting fair wage and good working conditions is something that should be fought for and supported.
This is important for me to do.
I agree. Companies need to provide for the people they are employing. If you are not getting your fair share, then striking may be the only way for your voice to be heard.
