they expect full-time employee availability while offering part time work, no real room for career advancement or even a hope to transition to a full time career (management positions are few in between), you're basically expected to be available whenever you're needed but when work slows down they have nothing for you, some questionable ethics when trying to get respondent participation

The list of cons will be longer: Abominable communication Suspect hiring practices Unclear motivations Lack of strategic planning Lack of insight Lack of job stability
