Intel

They started the 12-hour shifts with mandatory group calisthenics, done for about 10-15 minutes. This was an interesting concept to help prepare workers for long 12-hour shifts of standing the whole time.

Worked in an Intel 300mm wafer Fab as a Manufacturing Technician.

Semiconductor Fab Manufacturing Techs were assigned only 1-2 processes to do for an entire 12-hour shift and would not be allowed to cross-train into other processes for up to 2 years. In other Semiconductor Fabs, 2 years would be adequate time to cross-train across multiple manufacturing platforms.

It takes a very, very long time to become thoroughly trained in the Fab at Intel; they are way too overboard in their drive to be sure Techs know "how to do it right" before advancing the Techs.

The excessively lengthy time for cross-training results in burnout and disproportionate competition amongst the Techs. For that reason, I left Intel for better, much more progressive Semiconductor Fab opportunities.

Loosen up the excessively lengthy cross-training protocols. Learn to trust and embrace challenging the employees to advance accordingly to their own individual capabilities, instead of being so rigid. Don't worry, you won't lose control of manufacturing quality standards. Quite the opposite, employees will be encouraged to do the very best they can, resulting in highly sustainable quality yields and protocols.
