There are still a great many jobs where people are required to travel. Many people think of sales when traveling is a normal part of work. There are many specialists that travel on a regular basis. Engineers that specialize in large machine installation often travel as a normal part of their duties. They are on the road more days than they are at home. This makes it very difficult for them to maintain a relationship.
A large part of being in a relationship is physical contact and socializing together. A couple wants to be able to hug, kiss and cuddle. Without that physical contact, the relationship just isn't the same. Socializing is another area that is important in a relationship. Going to a cousin's wedding without a date is a lot less fun. Attending the annual company picnic alone is not the same. Even if people know a person's significant other must travel for work, it puts a heavy strain on the relationship when they are seldom available for social occasions.
People that travel for work have often found it is too difficult to maintain a relationship. Rather than deal with the complexities, they often turn to an escort agency for their dating needs. Escorts do not expect their clients to attend their family functions, so it is the perfect way to have companionship without commitment. It gives the traveler an opportunity to enjoy an evening out in company without getting into a relationship.
People that will continue to travel for their job might find the company of an independent escort to be their best bet. An independent works under the same rules as those that work for an agency, but they have their own client list. Spending companionable time with the same person on a regular basis may make it more enjoyable to spend some time at home.
