You want your boss to like you, right? Even if they do, it doesn't hurt for them to like you MORE. To increase their opinion of you, here's a simple tip. Access your work email at home via webmail. Then, reply to his/her emails at a time when you should NOT be at work. Like, say, 8:00 in the evening. Sooner or later, your boss will be mislead to believe that you are a hard, dedicated worker who puts in extra time. This can also be especially helpful if you know you'll be late to work. Before you take your shower, log on and send an email, just responding to work. He/she will think you're in your office, or just had to step out for a meeting. Works like a charm.
