Your employer appreciates your willingness to go above and beyond the call of duty. You're the last person to say 'it's not my job' when faced with an unpleasant task. As far as you're concerned, you'll do what's necessary to satisfy a client or complete a job. This accommodating attitude has strengthened your company's reputation. It has also put you in line for an impressive perk. Being able to work from home a few days a week will make life much easier.
