Yuneec cut off 50-70% of their employees in March 2017 and is still going strong. Autel in February, 2017 laid of it marketing and sale staff and they are stronger then ever.
Parrot laid off 30% of its workforce early 2017. I would suggest as projects come and go, so do the staff. DJI, Gopro, Dell, Apple, etc, etc, do it all the time... I wouldn't stress at this point
