Why is it important to make a contribution to improving work practices and procedures?

It is important to make a contribution to improving working practices and procedures because this makes everybody (including yourself) more happy with the working environment you are in and therefore makes everyone work more effectively and efficiently. Also if you did not contribute to improving your working practices and procedures and the rest of your colleagues did it would make you look like you do not care about it and it is unfair on everyone else who did.
