What you’re asking for is in the article. The “single sentence” is actually three paragraphs which explain why this is a concern.

> what exactly is causing the safety issues they claim

This is in the third of those three paragraphs in the article:

> The collective agreements are negotiated on a sector-by-sector basis, and employees are guaranteed the wages and working conditions that are standard across the sector. This allows for companies to operate on a level playing field, while avoiding the risk of any one employer distorting competition in the sector by imposing poor conditions on their employees.

Tesla doesn’t allow the employees to work under the same conditions as dictated by the agreed-upon standards.
