Earned wages being withheld from 5 employees who quit/were fired over the last 6 months

I recently had to quit my job due to extreme distress the work environment (mainly management) was placing on me. Because I resigned, they have withheld my last 6 days of wages (1 pay check and 1 extra day of work). They have also done this to multiple other employees over the past 6 months, probably longer. They discriminate against new hires, wont hire pregnant women. Not only this, but the company is not a safe place to work, there are no OSHA regulations in place, if you file a complaint the office manager will retaliate and get the owner to fire you by lying about you. The owner and the entire office team have blocked every single employee they have forced to quit or got fired. The owner will not respond to any of the previous employees pleas and has withheld paid days off that were earned as well. Can you tell me if there is anything that can be done to stop this company from ruining people's lives and from stealing their earned wages? Thank you in advance! Located in Texas
