It sounds like the company is facing difficulties in hiring a new cleaner after the argument with the previous cleaner. This situation can happen in any organization, and it's unfortunate that it has disrupted the cleanliness of the office. As an HR expert, I would recommend several solutions to address this issue. Firstly, the HR department should actively search for a new cleaner by advertising the job opening on relevant platforms and engaging with cleaning agencies. Secondly, the company could consider providing additional incentives or benefits to attract potential candidates. Additionally, temporary measures such as rotating cleaning duties among employees can help maintain a clean working environment until a new cleaner is hired. It is important for HR to communicate effectively with the employees, explaining the situation and the steps being taken to resolve it. Transparency and empathy can help alleviate any concerns or dissatisfaction among the staff. Ultimately, it is crucial for the company to actively address this issue and ensure a clean and hygienic workplace for its employees.
