My job's supposed 'flexibility' doesn't seem to work in my favor

When I got hired to work at the after-school program I am currently employed in, the manager had me take over for another employee who had left. After passing the CBEST, I realized that since I worked 4PM-8PM, it was entirely possible for me to work as a substitute teacher in the mornings, and as an instructor at the after-school program as well.

Unfortunately, last week I got some news from my manager that wasn’t good for me. It turns out they are changing my schedule to 3-7, which would probably be too early for me to be able to sub and get to work on time. It turns out the guy I replaced is coming back, and they are giving him his entire flipping schedule back, eliminating my ability to work a second job and bust my ass up to a marginal income.

I’m rather annoyed that the guy could just quit and come back with everything the way it was before, thus fouling up my schedule in the process. Granted I could work as a substitute instead of doing this, but I wanted to have the reliability of doing both (along with the combined income of both jobs).

Your manager is not doing the right thing here - the guy in the job gets first dibs on shifts, not the guy who quit and is coming back. You lose seniority when you quit - clock re-sets to zero.

Feh. Companies will do whatever they damn well please. A guy my husband works with was fired for sexual harrassment that bordered on sexual assault, as well as waving a knife around at a co-worker.

They hired him back.
