I am the HR Manager of the company. The department head came up to me and complaint that his staffs has been taking a lot of MCs, late for work and missing in action. We have given him 1st warning letter on July1st, yet still the same behavior occures. What should I do on my part,
1) To issue him a 2nd warning letter?
2) To speak personally to him and give him a verbal warning?
Appreciate the advise.
