Good news /Work Vent/...

So few days ago I asked my boss for few Saturdays off, he said ok which to me meant that I am back to working Monday through Friday... so he called me like an hour ago, yelling at me that just because he said OK to me having Saturdays off but that doesnt mean that I will work on Fridays... he said Fridays are slow and he doesnt need two people working on that day... well if I worked every other Friday that would mean that one week I would have only 32 hours I told him thats not enough hours so he tells me you can work every other Saturday, it was like talking to a retard so I told him if he doesnt like it I might not work at all... so imagine he tells me you can work 2 months and then leave and during this time he will find someone new lol who does he think I am an idiot? I will train someone new and then leave? I dont think so buddy so I told him I would come tomorrow for my money and my check and adios
I like the job but it is not worth it, I run this agency for him, he doesnt do anything and he treats me like this? I dont think so... time to move on if you cant appreciate it, good-bye
thanx for letting me vent
