job performance

It's expected that your personal life will sometimes seep into the job, right?  But what about when you live with the job(s)?  And they don't take kindly to long coffee breaks and grunts for replies?  The poor children, I think, knowing that sometimes I should just stay home from work.  Call the temp. agency.  Instead, I bring my dark mood to the office.  I slouch around and bah humbug their party.  Tomorrow I'll arrive with a fresh sense of purpose and duty.  But when can we talk about that raise?
