Including my former manager, everyone's husbands, wives, sons and daughters work here which definitely create preferences and unprofessionalism.
When I first joined the company, the place was still a depressing place to work but COVID brought out this company's real identity: they don't care about employees' health and lives as long as they can maintain their contracts. Most older employees are getting ready to retire and younger employees aren't going to stick around long enough to deal with bad managers and culture. They just keep hiring unqualified employees and work them to death till they quit. Avoid this L3 location at all cost.
