Without notice, my company delayed my (possibly everyone’s) December payment until January. I incurre 3-15k credit card balance per month traveling for my company . As you might imagine this was not a pleasant surprise as my reimbursement was also delayed; causing me to carry a statement balance and pay interest.
Someone told me they did this to make Q4 look better and that it was illegal to do so. Lots of frustration with HR lately.
