['i have a slacker coworker that drives me crazy he gets to work late everyday and does the minimum to get by', 'Is the boss aware or does he seem to skate by unnoticed?', "she is aware but doesn't feel the need to do anything about it. that's what makes it worse", 'Is there an HR department you can take it to?', 'not directly inhouse']
Sounds like it might be time to sit down with the boss and discuss your thoughts and feelings. If moral gets too low it's not good for anybody.
i get so frustrated with my slacker coworker
