UPS is already behind schedule following the surge last week in online orders.
The package delivery company announced on Tuesday that there is a small percentage of its packages that were already being delivered late by between one and two days as it attempts to work clear of a backlog made during Cyber Week.
A spokesperson for UPS said that delivery should return back to schedule by the end of Wednesday.
The company announced that it is expecting the vast majority of packages shipped from Thanksgiving through Christmas to arrive at their destination at time.
The UPS spokesperson added that the company had already resolved the problem that had created the delays earlier this week due to such high ordering online during Cyber Week.
The holidays have always been a frenzied time for the delivery companies, but the increased popularity of shopping online has made for even more packages they must process as well as deliver.
Cyber Monday this year was the largest ever shopping day online, with a record sales figure of $6.59 billion spent online according to data from the online analytics firm Adobe Analytics.
UPS predicts that from Thanksgiving to Christmas it will deliver more than 750 million packages. That figure is up more than 5% from 2016, when UPS handled 712 million packages during the holiday season.
The challenges during the holiday season have been increased due to the improved economy making it much harder for UPS, FedEx and other delivery companies to find the additional seasonal help necessary.
UPS this year hired more than 95,000 part-time seasonal workers for just the holidays. It hired that same amount for both 2015 and 2016.
As usual, UPS has leased more planes and has rented additional trucks to manage such a high volume of packages, and has assigned workers to offices across the country that are usually overloaded with business during this period.
The UPS spokesperson said the company was taking every necessary step to ensure it is serving the demand of its customers especially during the current holiday rush.
In addition, UPS told over 100 delivery centers in areas that have high demand that their drivers might be requested to work more hours until January 5, including as many as 70 hours over a period of eight days.
Over 250,000 UPS employees are represented by the Teamsters union and the union is not happy with the plan for extra work, and in a letter to the CEO at UPS David Abney said the move would be physically tolling on the workers and hinders the ability to spend time during the holidays with their families.
