I'm going to refuse to serve a customer during the minutes silence for Remembrance Day. I just don't think it's right to do.
Why would you work during remembrance day?
I'm a muslim and I think that it's ok to work during that time.
If you're on the clock then its expected to fulfill your duty at your job. However, if need be then you should take a moment out of your day specifically around the time you want to perform the act of silence. Be sure to let your boss know ahead of time so that they can have someone fill in during this time in order to not disrupt the flow of business.
I'm sure I can just not do my job that day.
You need to do your job still you can't just show up and not do anything or you won't have the job for long.
