How much more should one be compensated for excessive travel for a job?

I accepted a job a year ago that involved very little travel (10-20 days a year). Since then my job description has changed and my duties require me to travel 120 day per year or more, with trips sometimes lasting up to 3 weeks working an average of 15 hours per day, 6 or 7 days per week. Does anyone know of any resources that may help calculate an average of how much more "travel" jobs generally pay more than "in office" jobs.





Any help is appreciated.





Thanks|||Usually "travel" jobs pay the same as "office" jobs, the only difference is the company either pays or you get reimbursed for air fair, food, rental cars and hotels.|||Ella is correct - generally assuming the facts are known at the time of hire





That said, when your job CHANGED there should have been a discussion on a comp change





You should have a discussion with your boss about this ASAP and you should concurrently start looking for another job (Unless you love what you are doing and there is a real future)|||Is the company giving you a per diem when you travel? Money per day for incidentals? Maybe you could ask you boss to increase this amount since you are traveling more and for longer periods of time. (Per diem money is not taxable income) Or ask them for a raise in your salary. In our company both office and positions that travel more are paid the same. The only difference is college degrees or work experience.
