- Agree or disagree with post On the surface, the numbers in financial statements do present a snapshot of a company's financial position and performance. However, just looking at the raw numbers often doesn't tell the whole story or reveal underlying trends and relationships that are crucial for making informed decisions. Think of it like looking at individual pieces of a puzzle. Each number is a piece, providing some information. But to see the complete picture – the company's overall financial health, its performance over time, how it compares to its peers, and its potential future – you need to assemble those pieces using different analytical tools. For example: Horizontal analysis helps us understand how specific financial statement items have changed over multiple periods. Is revenue growing?

It’s normal to feel a little offended, but blowing up or shutting down won’t help your case. Better move is to stay calm and treat it like a misunderstanding or just the first step in the conversation. That way, you keep things respectful but still let them know the offer doesn’t sit right with you. It also helps to back up your response with facts. Bring in things like your experience, numbers, or any specific results you delivered. That can shift the conversation away from feelings and toward the value you bring. Agree or disagree with postarrow_forward
- Agree or disagree with the post When you get an insulting offer, the best thing to do is stay calm and professional. Try not to take it personally or react out of anger. Instead, ask questions to understand why the offer was so low. This helps you get a better idea of what the other person is thinking. After that, you can respond with a counteroffer that shows your value. Use simple facts like your skills, experience, and what others in your field are getting paid to back up your request. If the person still refuses to offer something fair, it’s okay to politely say no and walk away. Standing up for yourself in a respectful way shows confidence and helps others take you seriously.
