No but it should be.

I guess it was normal on one construction site i worked on, but that was because we employed an old alcoholic and nobody really cared. We also had Syrian refugees who refused to wear PPE as they carved up asbestos (or the father refused it on behalf of him and his son. I tried to talk to them about it and reported it to the government workplace safety people, who then just so happened to show up the one day the two guys weren't at work, weird)

What kind of job are you working? I'm a bit of an expert on slacking, I might be able to give you a tip or two
