What are the benefits of tile shaft?

The garbage is dying. After the probation period, it is about 1500, and the salary is nearly 2000, and it will basically not increase in the future. I think that year, our dormitory resigned together, which was really spectacular. What's even funnier is that everyone celebrates each other after resigning. The tile shaft is really hard! Although the post is outdated, I still want to remind future generations!
