Final answer:
The best step to take when dealing with a coworker who consistently fails to provide necessary information is to have a direct conversation with them to explain the impact on your work and ask for their input on preventing future situations. Escalating the issue to their manager or HR should be a last resort if the issue persists. Creating a paper trail by emailing the coworker and BCCing their manager and your manager can also be helpful.
Step-by-step explanation:
When dealing with a coworker who consistently fails to provide necessary information, it is important to take a proactive approach to address the issue. The best step to take would be to have a conversation with the coworker directly. Approach them calmly and explain the impact their actions have on your work and productivity. Ask them for their input and ideas on how to prevent these situations from happening again in the future. This helps foster open communication and collaboration, which can lead to a more productive work environment.
It is not recommended to immediately escalate the issue to their manager or HR, as this can strain relationships and potentially create unnecessary tension in the workplace. However, if the issue persists and the communication with the coworker does not yield any positive results, then it may be necessary to involve their manager or HR for further intervention.
Additionally, creating a paper trail by emailing the coworker and BCCing their manager and your manager can help ensure that everyone is aware of the situation and prevent unfair blame from falling solely on you.
