Start by not referring to them as cock workers. Even if that was an auto correct, the fact that you auto corrected to "cock" says a lot about your average communication. In general, if you want to be taken seriously then you need to conduct yourself in a professional manner. Remember that you are not there to be your employees friend, you are their manager, which doesn't mean you have to work on cracking the whip, but be aware of being overly friendly with your employees. Don't overshare personal details of your life, it isn't appropriate at work in general, but it certainly isn't appropriate to share those types of things with subordinates. Lead by example-be 5-10 minutes early for your shift every day, take on tasks other people might not want to do, never ask your employees to do anything you wouldn't be willing to do yourself, conduct yourself with integrity.
