When it comes to describing a job that is simply awful, there are many words that could replace "crap job". Instead of using profanity, consider using alternatives such as "terrible job", "miserable work", or "horrendous occupation". You could also try "awful task", "thankless employment", or "drudge work". Other options include "grueling job", "unpleasant labor", or "challenging position". Whatever phrase you choose, make sure it accurately reflects your feelings about the work itself while still maintaining a level of professionalism. Those who choose their words wisely are much more likely to be taken seriously in the workplace.
