My female manager seems to be spending a lot of one of one time with a young make collegue.
This involves leaving the office together, during work hours, to run errands. Errands that could be done by one person.
She is relieving him of duties which puts more work on others and he spends a lot of one on one time with him, including after everyone else has gone home.
The flirtatious behaviour has been noted by all collegues within the office and gossip is rife. Which seems very unproffesional.
Would you report this higher up the chain of command?
