Certain workplaces may have such kind of rules. However, I think that if a company wants its workers to wear uniforms, then they must also provide more than one suits. A person may not wear a single uniform for the whole month. They would need to wear a different suit as well. So, a company must also offer that as well.
The company policy is that you will have to wear the t-shirts once per week to the workplace as that is a way of marketing the company to the outside world. The long suit for working in the company have tags for each staff and they are 3 in number per staff. That is the one that you are expected to handle with care.
You can agree with me that some staff can be careless with the company properties such as the uniform when they paid no dime to make use of it.
