I don’t think this is sending the message they really want the public to receive.
It almost made me laugh. I come from a background of small business owners, often working on call seven days a week. I myself have mainly been in customer service or freelancing which has few days off, lots of being on call and I only get paid if I show up and keep working. So, I was surprised and then almost laughed out loud when I saw this come up on a website for a union. Source: The Media Union of BC
