back in harness
back in(to) (the) harness
Resuming one's daily work. I'm not thrilled to get back into the harness on Monday. When do you get back in harness after your trip?
*back in(to) (the) harness
Fig. back doing one's job. (*Typically: be ~; get ~.) I don't look forward to getting back into the harness next Monday. When my vacation is over, I have to get back into harness the very next day. I'm not looking forward to having to get back in harness after my trip abroad.
