Get your own phone. I have had the same number for probably close to 20 years now. Everyone I know or work for knows it. I don't even have a home phone for the last 6 or 8 years. Besides the privacy aspect, you are a young guy and this is your first real job. You probably won't be there long before moving on. Do you want all your contacts to lose touch because they only have your work number. What about when you are looking for your next job, do you want to list your work phone as a contact? Get a cheap straight talk plan and forget about it. I have people call me all the time that I haven't talked to in years but they can still reach me because I have my same number.
