Tesla said in January 2026 that it would end production of the Model S and Model X and convert that space at its Fremont, California, factory to build its Optimus humanoid robot, and news reports said the last cars rolled off the line in May 2026. When a product line ends, California workers may face new jobs, retraining, schedule or pay changes, and sometimes layoffs. The law gives you rights at each step: written notice of pay changes, pay for required training time, advance notice of a mass layoff, and full final pay.
Key takeaways
- Your employer generally must tell you in writing about changes to your pay rate or payday within seven calendar days, unless the change appears on a timely pay stub (Labor Code §2810.5(b)).
- Required training is generally paid work time, and hours spent learning a new line count toward overtime.
- A covered plant generally must give 60 days’ written notice before a mass layoff of 50 or more workers (Labor Code §1401).
- If you are let go, all final wages, including unused vacation, are due on your last day.
What Tesla announced
On its fourth-quarter 2025 earnings call on January 28, 2026, Elon Musk said Model S and Model X production would wind down the following quarter, giving the programs “an honorable discharge.” He said the line would be replaced with one designed to build Optimus robots. News reports in May 2026 said the final Model S and Model X units had left the Fremont line and that the space would be repurposed for robot production. Reports did not describe related layoffs.

Reassignment and retraining
When a line is retooled, workers are often moved to other lines or shifts. Most California employment is at will, so an employer can generally change duties or schedules going forward, but some rules still apply:
- Pay changes in writing. If your pay rate, overtime rate or payday changes, your employer generally must notify you in writing within seven calendar days, unless the change shows on a timely wage statement or another required writing.
- No retroactive cuts. Work you already did must be paid at the rate in effect when you did it.
- Training is work time. Time spent in required training, including classes before or after your shift, is generally compensable and counts toward daily and weekly overtime. See off-the-clock work.
- No discrimination or retaliation. Who gets reassigned, demoted or cut cannot be based on age, disability, pregnancy or another protected trait, or on a past complaint.
Example (hypothetical): Kevin, a paint-shop technician, is moved to a new robotics line and told to complete two weeks of online modules at home in the evenings. That time is generally paid work time, and if it pushes him past 8 hours in a day or 40 in a week, overtime applies.
If layoffs follow
California’s WARN Act covers facilities that employ, or employed in the past 12 months, 75 or more people. It generally requires 60 days’ written notice before a mass layoff of 50 or more employees within 30 days, a plant closure or a relocation of 100 miles or more. Workers who did not get required notice may recover back pay and benefits for up to 60 days (Labor Code §1402). Our guide to Cal-WARN notice rights explains the details.
| If your job ends | What the law requires |
|---|---|
| Final paycheck | Due on your last day if you are laid off (Labor Code §201) |
| Unused vacation or PTO | Paid out with final wages at your final rate (Labor Code §227.3) |
| Severance agreement | At least five business days to consider it and notice of your right to consult a lawyer (Gov. Code §12964.5) |
| Late final pay | Up to 30 days of waiting-time penalties if willful (Labor Code §203) |

Frequently asked questions
Can my employer cut my pay when I am moved to a new line?
Generally yes, going forward and with proper notice, as long as you still earn at least minimum wage and the change is not discriminatory or retaliatory. It cannot cut pay for work already done.
Do I have to accept a transfer to another shift?
Usually yes, unless a union contract or written agreement says otherwise. A disability or religious need may entitle you to an accommodation, and longer shifts can trigger daily overtime.
Is retraining time paid?
Generally yes, including any overtime it creates.
What if I am laid off without 60 days’ notice?
If Cal-WARN applied, you may be owed back pay and benefits for the missing notice period. Talk to a lawyer promptly.
