Murphy’s Work Laws

Murphy's Law applied to the workplace:

Don't be irreplaceable, if you can't be replaced, you can't be promoted.
Eat one live toad the first thing in the morning and nothing worse will happen to you the rest of the day.
Anyone can do any amount of work provided it isn't the work he is supposed to be doing.
If you are good, you will be assigned all the work. If you are really good, you will get out of it.(From)
