Job Issues

I am so ticked off with my job right now. It seems like every time I have plans to do something this time of year someone misses it up. Here's the crap that has been happening so far. Today I just recieved some news that another person is and has put in her two weeks and she's been there for at least 25 years. But she's quiting due to health issues which I understand that but hell if they don't hire someone soon I might just quit due to health reasons too because I am sick and tired of being the only one who takes the bull stuff that they toss my way. This week I have to pull a split shift today and Friday and on Sunday morning I have to work alone...I don't mind however Sundays are usually a busy balls to the wall kind of day especially after church. In my personal opinion and I hate to say this but I think that once the steakhouse reopens next door and that person quits my place of work is gonna sink like the Titanic...and once that happens I'll be one person who would be looking for another job if not sooner.
