Recruiters too. It's like they expect you to be available everyday with no life. I was working this temp position and the manager would request me back, even everyday. 2 of his employees ended up quitting on the spot. So the other day I told him I can't do x day but I can do all the other days and he never replied back but ignored me. I guess found other temp workers.
And yeah, with job interviews too when you tell them you have availability on most days besides two and they never contact back. And jeez, all these are unskilled labor jobs.
