Perhaps you have learned the hard way about how to keep your relationships with your coworkers on an even keel while you are at work. This is something that some people know how to do instinctively, but others have to learn what they can do and what they can not do to maintain good relations. However, learning to have good relationships at work with your superiors can be even harder. Knowing when to speak up and when to stay quiet can be hard, but can also be something you can learn through thoughts and by learning from those around you.
Relationships at work with your higher ups can be hard to navigate while you are on your first job. This is when you have no idea what you are doing and what is acceptable. What you can do, for your very first experience, is to think about how you treat your parents. You may have made mistakes, but think about what you think they wanted from you and what you should never say to them. This is a great basis for starting out with a new boss for the first time. You can then feel the person out and learn more about boss and employer relationships.
Sadly, not all relationships at work are going to be fair. You may get a boss that is very friendly, loves to tell you jokes and hear yours, and cares about what is going on in your life as it affects your job. Others are very closed off and even snotty about their position, and the last thing you want to do with them is to tell a joke or mention that your parents are moving away and you feel strange about it. Always start off cautiously to see what your boss shares with you, and then share a quarter of what they share in return. As time goes on, you learn and fall into a comfortable boss/employee relationship that works for them and you.
Some bosses are very business like, but are also very kind. They may laugh at a joke, but it may also not sit well with them that you are not serious at work. Others may see you being too quiet and they may wonder about your skills. These are questions about relationships at work that may only be answered through experience. You may also find what one superior likes does not go over well with another. Understand that you are going to make mistakes. Just make sure you learn from them.
If you are thrown in and are not sure about relationships at work, be careful who you ask for advice. There are going to be coworkers that are going to love to help you, but there may be a few that want to make sure you do not get what they think they have earned. Observation is the best way to learn about each boss or superior. You will soon learn about how to talk to them, what you can say and what is best left unsaid, and even better, when they are at their best so you know when to present new ideas and when to ask for a well deserved raise.
