If you need a job, it’s always advantageous to speak to someone you know, getting a foot in the door, instead of making a cold call. You should keep up with the trends in your industry by communicating with colleagues and learning from experts. Many industries are changing almost on a daily basis. Those who don’t pay attention could be left behind. And to improve the job that you already have, adhere to basic work etiquette such as showing up on time, meeting deadlines and over delivering instead of over promising.
