You are never put with a company on any semi type of normal schedule. Precarious work to say the least.
Constantly text at all hours of the day and night begging you to work some shift.
Very impersonal as every text message is worded in such a way as to appear to be directed to you specifically, but it isn'!. Phishing really! OR This could be AI, I'm not sure!
Then when they don't find you anything and you get tired of the constant barrage of texts, you can't get them to stop, without first asking politely and then getting angry at them.
