Employees at UST are simply a number, they don't care about you at all. From the very beginning you'll know you are a number because your email address will be a letter and your employee ID number, rather than your name. It is very much a foreign run company where you are easily replaced with the next person. Or your jobs are just sent offshore after a merger occurs.
The company is big brother and has people monitoring online communities for anything negative from employees, and will fire them without hesitation.
The HR Department is horrible, they don't respond to questions in a timely manner, and give you the run around. If you ask HR a question it is an inconvenience. Benefits aren't anything special, and vacation time is minimal. They did finally start to offer a 401k match in 2019 (although limited). All the HR systems they use are the most user unfriendly applications, and some of them appear to be homegrown apps too that give errors regularly.
Now, they are even selling employee data to outside firms so that they can send junk mail to your home.
