On Thursday CEO Jeff Bezos sent Amazon shareholders an annual letter that disclosed information about the company’s employee pay-to-quit program, grocery deliveries and – oh yeah – they are still moving forward with that drone delivery program. According to Bezos, Amazon is testing the fifth and sixth generations of their Prime Air aerial delivery vehicles, and the seventh and eighth generation drones are already in the design phase.

Bezos announced the program in December last year, admitting that though it is moving forward, it will still require years of testing and collaboration with the FAA to pin down regulations before it can come to life.

In more down to earth news, the company announced its “Pay to Quit” program, in which workers will be given $2,000 to quit, plus $1,000 for every additional year they have been with the company – up to $5,000. According to Bezos, the company makes this offer to employees for the general good of the company. “The goal is to encourage folks to take a moment and think about what they really want. In the long-run, an employee staying somewhere they don’t want to be isn’t healthy for the employee or the company,” he said in his letter.

The company also has big plans in the grocery world, expanding its $299 grocery delivery program by including more vendors in the already-existing Seattle market and expanding to include Los Angeles and San Francisco. They have also extended delivery to Sundays in many parts of the country and plan on expanding even further throughout the year.
