"We would like you to take the opportunity to refresh or spend time with your family, so Tesla will be giving you a full week pay for the week of January 4," Tesla added.

On Friday, in a separate email to staff, Tesla CEO Elon Musk said that the demand is "quite a bit higher than production this quarter," that's why he suggested employees ramp up production as much as possible for the rest of the year.

Series of temporary production shutdown

The temporary shutdown followed after a string of issues with both vehicles for the automaker made headlines. Tesla recalled over 9,000 Model X vehicles in late November due to a cosmetic adhesive that could fly off. The recall came after it initially recalled 15,000 Model X's due to power-steering problems and in October, 30,000 Model S and X over suspension problems.

Allegedly, staff on the production offered full pay for one week only with some paid holidays and were asked to take unpaid days off or accept "limited" work with Tesla's other sites during the production halt. According to MarketWatch via MSN, 

Tesla has not yet responded to a request for comment on Sunday, as per MarketWatch. On the other hand, it is not a typical move for Tesla to pause its manufacturing for a short period while it improves its production line. 

An end-of-the-year crush to deliver its vehicles is Tesla's traditional endearment to meet production targets and to comply with its January 1 deadlines for electric-vehicle tax breaks for its clients.

Earlier this year, the company targeted delivering 500,000 vehicles in 2020. It maintained the guidance in its third-quarter earnings report in October. S&P 500 index will join Tesla on December 21, and its stock has skyrocketed this year. Tesla's stock rose to almost 630% year to date compared to S&P's 13% gain.
